In order for the mindflayers to build new ships they could have struck a new deal with the arcane. As the arcane are lawful neutral the absoulute cannot be one of them. The mindflayers themselves seem to be inadept at dealing with netherese magic.
I guess the answer to the question "Who can build spelljamming ships and work with netherese magic" would point in the right direction.

It pretty much cannot be a drow matron. Lolth would not be happy about someone starting a new drow religion.

I sometimes use thought experiments. I don't necessarily believe in every idea I post for discussion on this forum
