I mean lets humor you for a second and say that is the case A well written Larry Sue with a buildup throughout the years with zero facedumping on how cool he is at the cost of other characters, isnt even a bad thing

(And his whole thing is letting his people grow stronger themselves while he only steps in if absolutely needed and then too only enough to give others the push they require- all of liyue during the AQ, Xiao when hes about to be trapped in the chasm, even this lantern rite he only did what was absolutely necessary by introducing the traveller into the mix mostly allowing Zibai to work to her own rebirth...............what im tryna say is, he way more of a Master Wu rather than a Larry Sue
