That's not really what the article is talking about. The article is referring to the fact that you can ask for specific verses in some version/translation (that are KNOWN) and the potential for the LLM to confidently generate a completely fabricated or subtly different copy.

And going a step further, any follow-up questions to the LLM will be using this incorrect copy as the source for interpretation causing it to go even further in the wrong direction.

Incidentally - this was occurring using a custom fine-tuned model with an added layer of RAG.
