Ask HN: Open-source AI generated project

If you use one of the tools like Claude Code / OpenAI Codes, these could be trained on copyrighted Code.

If I use one of these tools to make an app/plugin/..., do you think there will be legal problems if the code included was partially from commercial projects, that the LLM was trained on?

Codex once created PHP code, where in the generated code I could see a Copyright notice of another company - as if it was trained - in this case - on a commercial Magento 2 Module.
