The Inspired keyword triggers when the card becomes untapped. Does this include when it enters the battlefield initially, or only when it has already been tapped?
When entering the battlefield a creature does not "become untapped". "Becomes untapped" only refers to a creature going to the untapped state from a tapped state.
It must actually go from a state of being tapped to a state of being untapped. So no, you can't use the newly spoiled Kiora's Followers to untap an already untapped Inspired creature and get its effect because it was never tapped in the first place.

So no, Inspired also does not trigger on ETB.
