Maybe I have a silly solution,

Since you are using .git, then maybe you can create a .hg, .svn,
or what ever CVS tools other than svn,
in VeryImportantLambda folder, MoreImportance folder, and RunInCaseOfEmergency 
folder.

Then when you visit files in VeryImportantLambda folder,
then project.el will set the project root at VeryImportantLambda,
I think everything would just be fine there.
As long as you don’t launch eglot python lsp in the “actual” project (which is 
.git),
which for example is project_root/src/python/main.py
then everything should be fine.

Just have a try
where test is a .git folder and test/test2 and test/test3 are two .hg folder,
then eglot will launch two lsps at test2 and test3 folder.

You can just add .hg to your .gitignore and magit can used as usual with no 
pain.

This is a really stupid but I think with not too much effort try.
