I guess it depends on how and why they are used by the developer. Most of the code I write isn't bleeding edge stuff, and using a copilot as a thought partner is pretty useful.
If the client wants "something" and an LLM provides a significant percentage of "something" that looks good enough for the developer to get paid, that is definitely value for the developer. Might not be valuable for the client, but I'd claim the state of the industry before LLMs was generating plenty of software that wasn't actually valuable for the client anyway.
