The LLM can make a plan or outline first, which is also writing.

Any researcher already has this in their head long before any writing takes place.

I must be a bad researcher then because every paper I've written starts as a very vague "here are the overarching implications and important results". But the detailed order of results and the nuts and bolts of how to argue out the conclusions gets decided in drafting. Only the simplest of results I've had is essentially pre-written.

		>"here are the overarching implications and important results". That's the outline. I doubt an LLM would help much in deciding how best to present the finer details, as they will be very specific to your particular manuscript.
