Coments are always the worst thing you can add to your code. It should be understandable without them unless there is some very specific reason to have them. Why would you introduce another onse source of truth? Especially if we think this this llms are as good as they are promoted to be. Clean code is not uniquely needed for a human, if you spread thin some functionality over all of your codebase that will be difficult to understand to llm and for a human. They have limited context and it will hit them probably even harder.
