Unless I missing one, I believe the only moves of Labrys's with guard point is her DP, Beast supers and AoA (which starts pretty late). You should be able to easily beat her DP on reaction with a DP of your end if you can't block in time. The supers are supers so they shouldn't be a problem and AoA has guard point so late it shouldn't be able to be used to get out of good pressure.
Her pressure is good at higher axe levels but her mix-up isn't that great without RC (or cross-overs and throws) so you shouldn't be mixed-up that often. Though do be mindful of her frame traps since they really hurt at red axe level.
Kind of agree with you about combos ending with D super but it doesn't do much damage until it is high axe levels and it uses it all up so she is at a disadvantage if it didn't kill you and end the match.
