To me TT's tilt at setup does not seem to be due only to the natural tilt that might occur from the grip (right hand naturally lower than left).
He adds alot.
In TT Ch. 1 "Pivot" video you can see this starting at 3:40 but more cleary at around 7:04 he says after getting what he calls the "three point set" completed to "tilt just a bit": and you can see this clearly as a choice he is making to hula just a bit toward the target (as Mr. Fort has said he does) so it's clearly moving toward or is at an impact address for him before he starts his backswing.
