1. This interpretation might not be "true" but it is a good-faith effort that respects the text.
2. This LLM is fabricating verses, chapters, and even books of the Bible.
If you've used LLMs much, you know that #2 is not only possible, its quite common. This is the kind of "might not be true" that you should be aware of when using an LLM for apologetics—or any effort where "truthiness" is important.
The friction for me is I am just a very logical and evidence-driven person by nature, so while I recognize (at least for me) that there are some benefits to adhering to some religion or spirituality, the core Christian belief is really difficult for me and always has been. So I don't really know yet where I'll land.
Arguing that you can't use an LLM for Christian apologetics because it "might not be true" overemphasizes the definition of "truth" when it comes to scripture and those teaching Christian apologetics, which is entirely influenced by what doctrine you subscribe to.
All evidence so far indicates they will not make it right, but instead they may make it even worse. Your faith is wildly misplaced. Seriously, talk to a lawyer.
Keep in mind, just because you seek advice from a lawyer doesn't mean you need to take legal action against the school. Talking to a lawyer is not an escalation; the school doesn't even need to know you consulted one. A lawyer will advise whether you should take legal action and any more amicable alternatives available before they do anything on your behalf.
