They stay loyal because they need a reason to exist. With their power, even one of then is enough to take over the world. Kind of like how the past noc's rampage and have no purpose but to destroy. You also have to factor in that they were specifically created for the guild.

Plus ainz was the guild master and furthermore, the person who stayed till the end. He can be seen as the only person who stayed with them when they became sentient, and also the one who took care of them when everyone else left.

It's straight loyalty and also, they feel he cares for them.
