I made a script to check whether a PyPI distribution is free. The code repository is hosted in a Tor hidden service It's not very efficient, but here you are:

Checks if a PyPI distribution is nonfree, it takes into account all its
dependencies. The exit status is zero, unless a non-free distribution is
detected.
