I put together a little script to search for and list installed litellm versions on my systems here: https://github.com/kinchahoy/uvpowered-tools/blob/main/inven...

It's very much not production grade. It might miss sneaky ways to install litellm, but it does a decent job of scanning all my conda, .venv, uv and system enviornments without invoking a python interpreter or touching anything scary. Let me know if it misses something that matters.

Obviously read it before running it etc.
