Purely functional expression is not subject to copyright. If you claimed that your code was used to train an AI among thousands/millions of other code snippets and somehow your creative expression came out the other side, I would suggest what you are trying to claim is a purely functional expression and not subject to any meaningful copyright. And I would be correct.
