Re: Python bindings (`clang/bindings/python/clang/cindex.py`)
We `from __future__ import annotations` at the start of `cindex.py` which allows using the PEP 585 features (among others). 
We have a CI job that runs the libclang-python tests against 3.8 and 3.13, see here: https://github.com/llvm/llvm-project/actions/workflows/libclang-python-tests.yml

I have also tested this locally, and I can successfully run both the cindex tests and the mypy type checker on it with Python 3.8. (removing the future import produces the problems your PR would have resolved)

Besides, I see no reference to the libclang python tests in the build log you've linked.

Sidenote regarding the other files (which I'm not maintainer for, so cannot say much about them): consider doing the same thing there, to similarly import from future, instead of changing all generic collection types.
