[General] How would someone with the ability to tell when someone is lying register a statement that is literally untrue, but may or may not be metaphorically true?

Like, if Darth Vader said "Anakin Skywalker is dead. I killed him", how would that be registered?

Perhaps it would depend on whether the speaker really believes what he is saying.

This is the only real way for lie detection to work.  Otherwise you could use your magic lie detector, and have someone make wild guesses about basic physical facts until you discover all truth in the universe.
