I had a teacher once in highschool, an extremely competent one, but he was saying that a Hörst was a tecnonic valley and a Graben is tecnonic mountain. I had just come from an exchange in Austria and that sounded just wrong to me, because they mean the opposite in German. It turned out it actually was.

The same way a teacher doesn't substitute the texboook, LLM won't substitute DYOR. It'll help you understand where your flaws lie. The heavy lifting is still your job.
