Ainz doesn't know that with any certainty.

And actually, neither do we. Really, if the thing with Shalltear had gone a little differently (mind-control fully successful and Lady Kaire not killed), Nazarick could have been in deep doo-doo, Ainz killed while still tidying up the graveyard incident, probably Albedo charging out, waxing Shalltear, then getting herself mind-controlled in turn....

So no, not only does Ainz not know for certain that Nazarick is invincible, he has pretty solid evidence that it isn't, and if he's careless it could all be over, or at least so badly messed up that they'd never fully recover.
