I tried to follow the instructions here:
https://mypy.readthedocs.io/en/stable/stubgen.html
but the instructions about creating a stub for a C Extension are a little
mysterious. I tried to use it on the .so file without luck.

It says that stubgen works on .py files not .so files.

You will need to write the .pyi for your .so manually.
The docs could do with splitting the need for .pyi for .so
away from the stubgen description.

"Mypy includes the stubgen tool that can automatically generate stub
files (.pyi files) for Python modules and C extension modules."
I tried stubgen -m modulename, but it generates very little code.

From the .so I am struggling to figure out how it could ever work reliably.
I cannot see that there is enough information in a useful form to allow
the tool to work.
