The Guardians don't really have exercise free will, but it looks like that Morishita has successfully convinced them to defy what the Vatican said (really Linford), and simply fight with Lela.
Speaking of Lela, she's certainly taking her fight with Kaguya seriously. But Kaguya doesn't seem to be fighting with the same enthusiasm. She forced Lela's upgraded form and wings into the fight while seemingly not breaking a sweat!
