"The collecting society GEMA, which manages the rights of composers, lyricists and music publishers and has approximately 100,000 members, filed the case against OpenAI in November 2024."
Settlements can go undisclosed by agreement of the parties involved. Civil court is different from criminal; the former is for the benefit of interested parties, the latter is for the benefit of the public at large. Criminal courts can do some things behind closed doors as well but that usually requires a need of the state (such as protection of a judge, jury, state, etc.)
This is assuming a legal system similar to that in OPs post.
