It seems that the situation has now changed. Previously, thralls that fell through the mesh quickly died. Now the thralls also fall under the mesh, but do not die. Or they die less often. At least in a single player standalone game.
I recently ran an experiment on the EL map. There are places where a thrall or pet is guaranteed to fall under the mesh as soon as the player leaves the field of view. For example, opposite the northeastern entrance to Sepermeru, not far from the cliff. There are also places where you have to wait a little and the thrall may fall. I placed thralls in such places and after falling waited for many hours of play. Up to several tens of hours. And not a single thrall died, they could be saved at any time from the settings menu, of course, with the loss of equipment.
