[Airbenders are far from psychic (all the better for Hei). Discordance aside, there's nothing about Li that would arouse suspicion. Jinora's only suspicion where he's concerned is that Li plays dumb; he showed her once that he's not all puppy eyes and clumsy awkwardness. There might be a decent brain in his head.]

No, she doesn't. Benders' behavior tend to reflect their elements, and Korra's natural element is water.

[Jinora will keep feeding Li information. As someone who likes gathering information herself, she's more than happy to give it to others.] Not just here.
