Declare a project.el project for each directory that has a .venv.

I'm guessing you are currently using vc-project, so there is only one,
rooted where the .git directory is.

You do this by writing your own function for project-find-functions;
something like:

(defun my-projects (dir)
 (list 'transient (locate-dominating-file ".venv")))

(add-to-list 'project-find-functions #'my-projects)

You might have to delete vc projects from project-find-functions, or
make it buffer-local; there are lots of choices.
