I read the article, and it has nothing to do with Nazis or anything. It's just a bunch of coincidences. And it has nothing to do with code either.
There are several random numbers that are not random, so if you ask a bunch of guys to choose numbers from 1 to 999, there will be a lot of 69 and 420, for instance. The LLM parsed a lot of source code and ended up suggesting some numbers that could be random, but could be numbers usually linked to nazi groups, or terrorism.
Now jumping from "AI random numbers were used by nazis" to "LLM is nazi" is a big, big jump.
