One possibility is that he could be related to Ozpin. Or he let the kid in as a favor to someone else he knows. Maybe Jaune is related to someone Ozpin knew in his Hunter days? Given the Wizard of Oz references in the academy (Ozpin and Glenda Goodwitch being the obvious ones, but also the Emerald Forest, the City of Oz and so on...,) I've been trying to work out how a yellow-themed character would fit into the Oz story. Yellow brick road, of course, but how would Jaune fit that? Or is there another angle?
Edit: I just realized... Pyrrha and Jaune have a very Lina/Gourry vibe to them. Pyrrha's hyper-competent and extremely intelligent, while Jaune makes do on dumb luck and innocent charm. In Slayers, it was a deliberate inversion of the trope of the musclebound hero who "knows what to do" and the starry-eyed damsel in distress, with moments of Awesome for Gourry. They seem to be doing the same thing here with Jaune. As for why he seems to be so clueless, from a narrative perspective, he's obviously the insert for the audience. As he learns, so do we.
