What you mean by "enforcing copyright rules on AI"? Regardless of the tool used if the code used by someone heavily copies (against your license) on your code then it's copyright infringement, the fact that the tool is an AI doesn't really change this fact. But I guess you want to expand the copyright law to consider more than just the final product (code in this case), as it would be original in the vast majority of cases.
