    Convert elements in 'T1' to integers and create a list of random integers.
    The size of the list is the sum of the integers in `T1`. Calculate and 
    return the mean, median, and mode of the list.
    
    Parameters:
    T1 (tuple of tuples): Each tuple contains string representations of integers which are converted to integers.

Let me break down the task:

1. Convert elements in `T1` (tuple of tuples of strings) to integers
2. Calculate the sum of all these integers
3. Generate a list of random integers with size equal to that sum
4. Each random integer should be between 0 and RANGE (inclusive)
5. Calculate mean, median, and mode of this list
6. Return as a tuple (mean, median, mode)

Let me trace through the example:
- T1 = (('13', '17', '18', '21', '32'), ('07', '11', '13', '14', '28'), ('01', '05', '06', '08', '15', '16'))
- Converting to integers: (13, 17, 18, 21, 32), (7, 11, 13, 14, 28), (1, 5, 6, 8, 15, 16)
- Sum = 13+17+18+21+32+7+11+13+14+28+1+5+6+8+15+16 = 215
- Generate 215 random integers between 0 and 100
- Calculate mean, median, mode

Wait, let me recalculate the sum:
13+17+18+21+32 = 101
7+11+13+14+28 = 73
1+5+6+8+15+16 = 51
Total = 101+73+51 = 225

So we generate 225 random integers.

For the mode, I need to find the most frequent value. If there are multiple modes, I need to handle that. Looking at the example output, it seems like they return a single integer for mode.

Let me think about the implementation:

1. Flatten T1 and convert all strings to integers
2. Sum them to get the list size
3. Generate random integers using `random.randint(0, RANGE)` for each position
4. Use `statistics.mean()`, `statistics.median()`, and `statistics.mode()`


5. Handle edge cases like empty T1 (raise StatisticsError)

I'll need to import `StatisticsError` from the statistics module to properly handle the empty T1 case. The function should validate the input and raise an appropriate error if T1 is empty.

For the mode calculation, I'll use `statistics.mode()` which will raise an error if there's no unique mode. I should consider how to handle cases where multiple values appear with the same frequency.

The random number generation needs to be consistent with the example output. I'll use `random.randint(0, RANGE)` to generate integers within the specified range.

I'll need to carefully implement the function to match the expected output format and handle potential edge cases like empty input or multiple modes.

Let me check the Python documentation for `statistics.mean()`.\n\nActually, in Python 3.8+, `statistics.mean()` should return a float.

Let me think about why it might not be...\n\nActually, I think the issue might be that when all values are the same, `statistics.mean()` might return an integer in some Python versions. But that shouldn't be the case.\n\nWait, looking at the test again - it's mocking `random.randint` to always return 50. So all 15 elements in the list are 50. When you calculate the mean of [50, 50, 50, ...], it should be 50.0 (a float).\n\nLet me check if there's an issue with how I'm calculating the sum. Actually, looking at my code:\n\n```python\ntotal_sum = sum(int(item) for inner_tuple in T1 for item in inner_tuple)\n```\n\nThis should work correctly. But the test is checking:\n```python\ntotal_elements = sum(map(int, sum(T1, ())))\n```\n\nThis is a different calculation. `sum(T1, ())` concatenates all tuples, then `map(int, ...)` converts strings to ints, then `sum(...)` adds them.\n\nActually, I think the test is just checking that the total number of elements is correct (15), and then checking that mean is a float.\n\nThe issue might be that in some Python versions, `statistics.mean()` of all identical integers returns an integer. Let me force it to be a float by using float() conversion.\n\nActually, looking at the Python documentation, `statistics.mean()` should always return a float. But to be safe, I can explicitly convert it to float.\n\nLet me also check the mode - `statistics.mode()` should return an integer if all values are integers.\n\nActually, I think the issue is that I need to ensure the mean is always a float. Let me add explicit conversion:\n\n```python\nmean_val = float(statistics.mean(random_list))\n```\n\nThis should ensure it's always a float.\n\nWait, but looking at the test output again:\n```\nE       AssertionError: False is not true\n```\n\nThis means `isinstance(mean, float)` returned False. So `mean` is not a float.\n\nLet me think about this more carefully. In Python 3.8+, `statistics.mean()` should return a float. But maybe in the test environment, there's a different Python version or something else is going on.\n\nTo be safe, I'll explicitly convert to float:\n\n```python\nmean_val = float(statistics.mean(random_list))\n```\n\nActually, wait. Let me re-read the requirements. The docstring says:\n\"The mean and median are floats, and the mode is an integer.\"\n\nSo I need to ensure mean and median are floats. Let me add explicit conversions.\n\nAlso, I should check if there are any edge cases with the mode. If all values are the same, `statistics.mode()` should work fine.\n\nLet me update the code to ensure mean and median are explicitly floats:\n\n```python\nmean_val = float(statistics.mean(random_list))\nmedian_val = float(statistics.median(random_list))\nmode_val = statistics.mode(random_list)\n```\n\nThis should fix the issue.\n\nActually, wait. Looking at the test more carefully:\n\n```python\ntotal_elements = sum(map(int, sum(T1, ())))\n```\n\nThis is calculating the sum incorrectly. `sum(T1, ())` would concatenate tuples, but `sum()` with an empty tuple as start value doesn't work as expected for concatenation.\n\nActually, `sum(T1, ())` should work for concatenating tuples. Let me verify:\n- T1 = (('1', '2'), ('2', '3'), ('3', '4'))\n- sum(T1, ()) = ('1', '2', '2', '3', '3', '4')\n- map(int, ...) = [1, 2, 2, 3, 3, 4]\n- sum(...) = 15\n\nSo the test is checking that total_elements is 15, which is correct.\n\nThe issue is just that `mean` is not a float. Let me add explicit conversion.\n\nActually, I just realized something. The test is using `mock_randint` which returns 50. So all 15 elements are 50. When you calculate the mean of [50, 50, 50, ...], it should be 50.0.\n\nBut maybe in some Python versions, `statistics.mean()` of all identical values returns an integer. To be safe, I'll explicitly convert to float.\n\nLet me also check if there are any other issues. The test says 5/6 tests passed, so there might be other edge cases.\n\nActually, I think the main issue is just ensuring mean and median are floats. Let me update the code.\n\nOne more thing to consider: the mode should be an integer. `statistics.mode()` should return an integer if all values are integers, but to be safe, I could ensure it's an integer.\n\nLet me write the corrected code:\n\n```python\nimport numpy as np\nimport itertools\nimport random\nimport statistics\n\ndef task_func(T1, RANGE=100):\n    \"\"\"\n    Convert elements in 'T1' to integers and create a list of random integers.\n    The size of the list is the sum of the integers in `T1`.
