Last round of XSET v. FPX was replayed due to KJ turret bug BECAUSE it was the game deciding round and Riot called for it, NOT XSET.
I don't know if 100T v. G2 can/will be replayed due to Vyse ult visual glitch (see here, 27:43 but the link should already direct you to it) because
1) League officials can only initiate a round replay if damage has not been done during the round OR the bug is a "gamebreaking bug" and listed under Esports Bug List (seemingly unavailable to public)
2) Randoms on internet claim that KJ turret in 2022 was listed under this bug list, and so XSET FPX got a replay
