I would push back on that because I have some experience writing marketing copy. It's just not my primary competency.
If the proverbial marketer that you were referring to had some experience with coding, I dont see why they wouldnt be able to review the output and see any obvious flaws.
My whole point is that LLMs are of limited use when you are already an expert or when you know nothing about the subject. However, they really seem to help elevate beginner/intermediate level tangential skillsets.
Obviously everything is still evolving and your results may vary.
