Let me analyze the problem:

1. We have a tuple of tuples containing string representations of integers
2. We need to convert all these strings to integers
3. Create a list of random integers where the size equals the sum of all these integers
4. Return the 25th, 50th, and 75th percentiles of this list

Let me trace through the example:
- T1 = (('13', '17', '18', '21', '32'), ('07', '11', '13', '14', '28'), ('01', '05', '06', '08', '15', '16'))
- Sum of all integers: 13+17+18+21+32 + 7+11+13+14+28 + 1+5+6+8+15+16 = 101 + 73 + 51 = 225
- So we create a list of 225 random integers (0 to 99, since max_value=100 is exclusive)
- Then compute percentiles

For the random generation, I need to use `random` module. The random integers should be in range [0, max_value).

For percentiles, I can use `numpy.percentile` or `np.percentile`.

Let me think about the implementation:

1. Flatten the tuple of tuples using itertools.chain
2. Convert strings to integers
3. Sum them up
4. Generate random integers using random module
5. Compute percentiles using numpy

Let me check: `random.randint` vs `random.randrange`. Since max_value is exclusive, I should use `random.randrange(0, max_value)` or `random.randint(0, max_value-1)`.

Actually, looking at the example output with seed 42, let me verify:
- With random.seed(42), generating 225 random integers in range [0, 100)
- The percentiles should be (24.0, 48.0, 77.0)

Let me implement this step by step:

```python
import numpy as np
import itertools
import random

def task_func(T1, max_value=100):
    # Flatten and convert to integers
    all_ints = [int(x) for x in itertools.chain.from_iterable(T1)]
    total = sum(all_ints)
    
    # Generate random integers
    random_list = [random.randrange(max_value) for _ in range(total)]
    
    # Compute percentiles
    p25 = np.percentile(random_list, 25)
    p50 = np.percentile(random_list, 50)
    p75 = np.percentile(random_list, 75)
    
    return (p25, p50, p75)
```

Wait, I need to be careful about how numpy computes percentiles. By default, `np.percentile` uses linear interpolation. Let me check if the example matches.

With seed 42 and 225 random integers in [0, 100), the percentiles should be (24.0, 48.0, 77.0).

This looks correct. Let me finalize the solution.

    "reasoning": "The tests are mocking `random.randint`, but my implementation uses `random.randrange`.\nThe test cases expect `random.randint` to be used.\nLet's check the difference: `random.randint(a, b)` includes `b`, while `random.randrange(a, b)` excludes `b`.\nThe problem says `max_value` is the upper bound, exclusive. Default is 100.\nBut the tests mock `random.randint`. If I use `random.randint(0, max_value - 1)`, it would match `randrange(max_value)`.\nWait, the tests mock `random.randint` and set a return value. They expect the percentiles to be exactly that return value when all random numbers are the same.\nIf I use `random.randint(0, max_value - 1)`, it will be mocked correctly.\nLet's change `random.randrange(max_value)` to `random.randint(0, max_value - 1)`.\n\nWait, `random.randint` takes two arguments. The tests mock it with `@patch('random.randint')`.\nSo I should call `random.randint(0, max_value - 1)`.\n\nLet's verify:\n`random.randint(0, max_value - 1)` generates integers in `[0, max_value - 1]`, which is the same as `randrange(max_value)`.\nThe tests mock `random.randint`, so they will intercept calls to `random.randint`.\nIf I use `random.randint(0, max_value - 1)`, the mock will return the fixed value, and all generated numbers will be the same, so percentiles will be that value. This matches the test expectations.\n\nLet's adjust the code:\n```python\nrandom_list = [random.randint(0, max_value - 1) for _ in range(total)]\n```\n\nWait, what if `max_value` is 0? The problem says default is 100, and it's an upper bound. It's safe to assume `max_value > 0`.\n\nLet's check the test cases again.\n`test_case_1`: mocks `randint` to return 50. Expects p25=50.\n`test_case_2`: mocks `randint` to return 30. Expects p25=30.\n`test_case_3`: mocks `randint` to return 75. Expects p25=75.\n`test_case_4`: mocks `randint` to return 10. Expects p25=10.\n`test_case_5`: mocks `randint` to return 90. Expects p25=90.\n\nAll tests expect that when `randint` is mocked to a constant, the percentiles are that constant.\nSo using `random.randint(0, max_value - 1)` is correct.\n\nOne detail: `random.randint` is inclusive of both endpoints. So `random.randint(0, max_value - 1)` covers `[0, max_value - 1]`, which matches `randrange(max_value)`.\n\nLet's rewrite the function accordingly.\n\n```python\nimport numpy as np\nimport itertools\nimport random\n\ndef task_func(T1, max_value=100):\n    all_ints = [int(x) for x in itertools.chain.from_iterable(T1)]\n    total = sum(all_ints)\n    random_list = [random.randint(0, max_value - 1) for _ in range(total)]\n    p25 = np.percentile(random_list, 25)\n    p50 = np.percentile(random_list, 50)\n    p75 = np.percentile(random_list, 75)\n    return (p25, p50, p75)\n```\n\nWait, should I keep the docstring? Yes.\nIs there any other issue? The tests use `@patch('random.randint')`. This patches the `randint` function in the `random` module. My code imports `random` and calls `random.randint(...)`, so it will be patched correctly.\n\nLet's double check the exact signature and imports.\nThe prompt says:\n```python\nimport numpy as np\nimport itertools\nimport random\n\n\ndef task_func(T1, max_value=100):\n    ...\n```\n\nI will provide the complete file.\n\nOne minor point: `np.percentile` returns floats. The tests compare with `self.assertEqual(p25, 75)`. In Python, `np.float64(75.0) == 75` is True. So it should pass.\n\nWait, `random.randint` might be called with `max_value` directly in some implementations? The problem says `max_value` is exclusive upper bound. So `max_value - 1` is correct for `randint`.\n\nLet's test locally in mind:\n`T1 = (('13', '17', '18', '21', '32'), ('07', '11', '13', '14', '28'), ('01', '05', '06', '08', '15', '16'))`\nSum = 13+17+18+21+32 + 7+11+13+14+28 + 1+5+6+8+15+16 = 101 + 73 + 51 = 225.\n`random.seed(42)`\n`random.randint(0, 99)` called 225 times.\nThe example output is `(24.0, 48.0, 77.0)`.\nMy code should produce that if `random.seed(42)` is set before calling. The example sets seed before calling. So it's fine.\n\nOne thing: `random.randint` vs `random.randrange`. The tests explicitly mock `random.randint`. So I must use `random.randint`.\n\nI will construct the final solution.\n\n```python\nimport numpy as np\nimport itertools\nimport random\n\n\ndef task_func(T1, max_value=100):\n    \"\"\"\n    Converts elements in 'T1', a tuple of tuples containing string representations \n    of integers, to integers and creates a list of random integers.

The problem says exclusive upper bound, default 100. It's safe.\nIs there any chance `random.randint` is expected to be called with `max_value` directly? Sometimes problems are sloppy and say \"exclusive\" but actually use `randint(0, max_value)`. But `randint` is inclusive. If they meant exclusive, `randint(0, max_value - 1)` is correct. Given the tests mock `randint` and don't check arguments, it doesn't matter much for the mock, but for correctness `max_value - 1` is right.\n\nLet's verify the example output with `random.seed(42)` and `random.randint(0, 99)`.\nActually, `random.randrange(100)` and \n…[5486 chars elided]…\nening, conversion, sum, random generation, percentiles.\nUses `random.randint` to satisfy mocks.\nReady. \nOutput Generation. \n(Self-Correction/Note during generation prep)\nI should make sure `itertools` and `random` and `numpy` are imported as requested.
