Almost off-topic, but got me curious: How can I measure this myself? Say I want to put concrete numbers to this, and actually measure, how should I approach it?

My naive approach would be to just implement it twice, once together with an LLM and once without, but that has obvious flaws, most obvious that the order which you do it with impacts the results too much.

So how would I actually go about and be able to provide data for this?
