Hey the lusus theory would be fun to explore, since killing off the grubs and trolls would kinda be a hassle and not really a sure method they could just kill the lusii and wait for nature to do its thing

Specially if their Lusii have something to do with the reason they were made to go extinct in the first place- I still think it’s suspicious that there was a random First Guardian Axolotl and a Limeblood with an Axolotl avatar.
