Platonic's archetype is specificially the "Phantom Thief" archetype, not the "Lady Thief" archetype. Lady Thief is a cultural translation that we determined isn't really exact enough. Mayrana's Shadow Warrior archetype, unless I'm mistaken, is also a Japanese archetype, so saying it's a precedent for adding the Lady Thief one is a bit fallacious.

Besides which, Elluka actually commented on the archetype in-universe, while nobody has done so for Platonic

Quoting the wikipedia article on it: "A gentleman thief or lady thief, or phantom thief (怪盗, Kaitō) in the East, is a particularly well-behaving and apparently well bred thief." It's practically the same thing, so I can't see why we shouldn't add it.
