Interesting enough, none of the pillar men actually have accents. I guess it's a way to make them stand out from all the other characters in Part 2.
Actually,
Esidisi has a kind-of British accent. At least, he sounds like the actor is putting one on. You can sort of hear it in the episode where they first awaken, and during his fight with Joseph. Source: Have watched the dub full way through twice.
