Sounds like you’re just googling it rather than actually speaking from experience.
Like I said, I’ve used pre-commit for multiple years now. If you can run your lints from a command line, you can configure pre-commit to run them.
The project I’m working on has multiple sub-projects and those each have their own venvs, pyproject.tomls, etc.
Monorepos definitely make things a bit trickier, but again, you absolutely can write a local pre-commit hook that runs a bash command or script that 1.) activates the necessary venv and 2.) runs the lint command. I know this because I’ve done it, multiple times.
