It isI think I'm right in saying that gaseous nitrogen is less of a problem, say, if you have a leaking cylinder, because it won't expand that much when released. Liquid nitrogen, on the other hand, expands to something like 700 times its volume when it boils, which is why it drives all the oxygen out of the room. And all the while, you don't feel a thing, apparently.

Depends on how big the leak isIf there's enough escaping, it'll displace the air. Remember a new cylinder is at 230 bar, so will produce 230 times its own volume when it's at 1 atmosphere, or thereabouts.
