Code Review

This PR upgrades the litellm dependency. This is a good maintenance step, but it carries a risk. The new version might be stricter and cause our current implementation for requesting JSON output to fail. I've added a comment with details on the potential issue and where to look. Also, please remember to update the pdm.lock file to reflect this dependency change, as noted in the PR checklist.
