No, you have similar experience as a lot of people have.
LLMs just fail (hallucinate) in less known fields of expertise.
Funny: Today I have asked Claude to give me syntax how to run Claude Code. And its answer was totally wrong :) So you go to documentation… and its parts are obsolete as well.
LLM development is in style “move fast and break things”.
So in few years there will be so many repos with gibberish code because “everybody is coder now” even basketball players or taxi drivers (no offense, ofc, just an example).
It is like giving F1 car to me :)
