Are you referring to something more technical, or do you just not understand how LLMs work?

They are no more beholden to "human safety and goals" than any individual human is, and anyone telling you we can make deterministic guarantees about their output is making a category error.

LLMs do not "have motivations", they reproduce a model of human motivations embedded into their weights. This includes the full spectrum of human desires, not just the positive ones. If we tried to remove all examples of lying, or disagreement, etc. from the training data we'd have basically nothing left. Even the sycophancy we treat as aligned is basically just the other side of the lying coin.

No, it does not include the full spectrum of human desires. After pre- and mid-training, the extensive RLHF and RLVR post-training steps cause mode collapse, i.e., their output distribution is intentionally narrowed to a subset of (hopefully beneficial) behaviors and skills.

You don't (need to) remove lying from the data to do this – in fact, if you did, the model wouldn't have a very good model for what lying is, which is not very helpful in the real world. Instead, you mode collapse the model towards truthful behaviors.

To your other point: where did you get the idea that I think they're beholden to human safety or goals? I just said an aligned model is one that is compatible with said safety and goals (which is probably not a great definition of alignment, but it's certainly not claiming any deterministic guarantees).
