I’m not a programmer, so I can’t really do it myself. Is it allowed for me to go to some random dude, pay him 20 bucks to write the code, then have him add it to the GitHub?
(If you’re wondering what the app/feature is, I want to be able to shuffle play on the findroid app like you would be able to on the jellyfin web interface )

This is the repository? They have a ko-fi link in the repository meaning they accept donations to support the development. Have you tried contacting the lead developer of the project and asking if they would be interested in adding the feature you want if you sponsored it via a donation?
This is a good idea. It’s a lot easier to incentivize a maintainer who is already familiar with a project and invested in it with some money than it is to get a person who is unfamiliar with a project.
How much you should donate and how likely they are to agree depends on how complex your request is, whether they feel it fits in with the project for other people, and how busy they are.
