There’s no such a word as plagiarism in free licenses nor in copyright laws. One could violate copyrights or patents or not. Copyleft licenses do not forbid what you call plagiarism. If you want to forbid this as well as training LLMs on your code, you need a new type of license. However I’m unsure if such a license could be considered free by FSF or approved by OSI.
So, everything depends on how you define substantial similarities. My opinion is that if there are no copy-and-pasted chunks of code (except for trivial), there are no substantial similarities.

Plagiarism is a form of copyright infringement if there are substantial similarities.
Open source licenses build on top of intellectual property laws.
Licenses like GPL were made to destroy copyright from the inside

I live in another country, however the idea is the same as I wrote above: this all is about direct copying.
