Life doesn’t end, …it changes.
I'm presuming you haven't seen the VA list yet. The VA list confirms that Kukui is in the episode, but none of Ash's classmates( Lillie, Lana, Kiawe, Sophocles, and Mallow) are listed so it's unlikely that they would be in the episode.
And Prof Kukui is a bystander. Keyword is "or". And I was half joking since I knew she nor any background people would be watching the battle.
