The quotes are not laws, and those quotes are from the Copyright Office’s official statement on AI generated material. Please, just click the link at the bottom of my earlier comment. Here, I’ll even link it again:

If something cannot be copyrighted, it is in the public domain.

It doesn’t really matter if it’s not international law. If I don’t want to follow your open source license requirements, and your project is public domain in the US, I’ll just copy it in the US, and you can’t sue me.

Ok, I’ve editing my earlier comment to explain what I’m linking there, since it seems that neither you nor anyone else bothered to click that link.
