It's been pretty underwhelming. My use case was a crowned pulley with 1mm tooth pitch (GT2) which is an unusual enough thing that I could not find one online.

The LLM kept going in circles between two incorrect solutions, then just repeating the same broken solution while describing it as different. I ended up manually writing the code, which was a nice brain-stretch given that I'm an absolute noob at OpenSCAD.
