His fear of Ainz wiping out humans is not consistent with the honorable treatment he and his people received at the tomb. Resolving that inconsistency through communication and investigation is the first thing to do, not randomly suicide your entire race against a god.
He's not particularly plotting anything. Like he said, they can't start to collect members for the alliance in the first place, someone else would need to do it. That's quite a stretched goal, more like wishful thinking. In the mean time he has little choice but to wait for the terms of the alliance.

Since they were invited, there had to be a diplomatic dimension in what Ains was doing. Otherwise they wouldn't have been invited. No need to invite them to be killed since he could have killed the emperor back on the empire's soil as well. It doesn't really change that much, it only creates the possibility that Ains is not aiming to slay all humans. However, after this it's logical for the emperor to expect Ains to try to conquer lands without killing the population. If he's not mentally prepared for that, he's not fit to be an emperor.
