I'm tired of this pseudointellectual reductionist response. It's not "literally by accident" when they're trained to do something, as if we are not also machines that generate next actions based on learned neural weights and abstract (embedded) representations. Your issue is with semantics rather than content.
Obviously "hallucinate" and "lie" are metaphors. Get over it. These are still emergent structures that we have a lot to learn from by studying. But I suppose any attempt by researchers to do so should be disregarded because Person On The Internet has watched the 3blue1brown series on Neural Nets and knows better. We know the basic laws of physics, but spend lifetimes studying their emergent behaviors. This is really no different.
