When I got my Phoenix, I also received a game message saying "Your new pet has been automatically insured". In the main game, pet insurance is run through Probita in East Ardougne. If you die with an insured pet, you may rebuy that pet from Probita for 1 million gp. However, you can't exactly travel to East Ardougne to rebuy a pet in the Twisted League, so how does the automatic pet insurance work?

The League Tutor, located in Kourend Castle Courtyard, will allow you to reclaim lost pets. Note that it is not clear whether this will cost 1 million gp.
From the wiki page about the Twisted League update (emphasis mine):

@Cookiezzz has shared with us that reclaiming the pet is, in fact, free! Any costs that are applied in the normal game, should not apply in Twisted League.
