I'm afraid I have no alternative. The LilyPond 2.23.x version in 
flatpak doesn't currently work. I don't know when it started breaking, 
as I usually tested the stable only.
I opened a PR which makes 2.23.x work again:
https://github.com/flathub/org.frescobaldi.Frescobaldi/pull/14

openLilyLib is used by a small number of users, I think, probably not 
even using flatpak. In case of problems they can still download and use 
the official LilyPond binaries.

I don't know. Do you know some Python libraries which may need a 
similar feature?
