The way I imagined it, they don't even know that the war ended or what its outcome was. They would have shut themselves off to the outside world, only paying attention to it if they were somehow discovered. Obviously they would have sentries posted to watch the sky below for any potential outsiders, but that doesn't mean they know what world events are happening. They would be discovered either through a clue Tenzin locates at one of the air temples or from a past Avatar, like Yangchen, informing Korra.
Mon, I'm not sure I agree with the basis of a "cult of Aang." The Avatar already has to overcome bias since they come from 1 nation (and 1 place within that nation). Simply having a much smaller nation wouldn't make this bias any more difficult to overcome. In fact, it isn't much different from before since, as far as we know, there were no differing factions of air nomads. Sure, there were the 4 temples, but we've seen no evidence to state that any 1 temple had any reason to have a different philosophy from its counterpart temple (since there were 2 male temples and 2 female temples) or the opposite gendered temples. So they pretty much were a small group (in proportion to the world) that was one big family. The new air nation shouldn't be much different.
So long as Tenzin teaches his children properly, they do the same for their kids, and so forth, then I find it very unlikely for even one person to turn "rogue." For your cult theory, basically the entire family would have to turn rogue (or at least the powerful majority). I could see an airbending villain at some point if we had more of them, but right now they're really only focused on repopulating. But with my idea of finding a lost civilation of airbenders, they would finally be able to integrate airbenders into the modern society (like on pro bending teams) and we could even get a good airbending villain. Perhaps the leader of the group decides to strike back at the world, blaming the fire nation for obvious reasons and everyone else for failing to help. Then it would be up to Korra, with help from Tenzin and his kids, to defeat him and convince the airbenders to come back into the world.
