Or you've simply misunderstood what I've said despite your two decades of experience and education.
If you train a model on a bad dataset, will it give you correct data?
If you ask a question a model it doesn't have enough data to be confident about an answer, will it still confidently give you a correct answer?
And, more importantly, is it trained to offer CORRECT data, or is it trained to return words regardless of whether or not that data is correct?
I mean, it's like you haven't even thought about this.
