But if you don't want to and still want to use an LLM, there are low-bar choices you can make (using a technical writing skill, using ASD-STE100 Simplified Technical English, choosing your audience, proofreading at the end with human eyes to make sure it makes sense and doesn't repeat itself uselessly).
I think it shows either a) low respect or consideration for your audience or yourself, or b) laziness.
Trust yourself to write even if it's bad. At least it's human.
Hard things are hard. They’re not easy. But they’re worth it.
