When looking at Ilima, the only two possibilities I can think of for her specialty are either Normal types due to her clothes, or Fairy types due to her pink hair
For the amount of times we've seen Alolan Ratticate/Gumshoos Totem pokemon, plus the low levels we've seen the player's pokemon having during the demos of fights with it, it would likely be the first totem pokemon we encounter. Both of the Totem pokemon share the normal typing, and because so far we haven't seen any Totem pokemon with different types to the captains of thier trial, Ilima is very likely a Normal-Type specialist.
Edit: We also know that the Totem fight takes place on Melemele Island, making it all the more likely. Whitney's hair was pink too, and she was a normal-type trainer.
