First thing, the light novels that are the source material for the monogatari series are each written from the perspective of a particular character. That starts with Araragi, but a substantial part of the series is written from the perspective of other characters. Hanekawa, Nadeko, Kaiki and Kanbaru each have an arc written from their perspective and with Araragi barely in the story. Also, my understanding is there are a number of post "final season" stories that also have alternative POV characters. At least one of those stories has Araragi never appear, though he is mentioned.
Edit: On an unrelated note, I'm a bit interested in how Leila might handle a commission of parts of the Berserk manga. It's just because of the recent boost in people making videos about it, but what I see makes me wonder if it would be something that Leila would have fun analysing in the way she does.
