I see. Is there a reason Thorne and the Free Cities shun the pantheon and the magic, or is it simply a matter of taste and culture?
I'm not certain relying on those Summoned from Solvunn to confirm or deny your theory is the best option, even if it is currently our only one. But neither would I count myself as unbiased. But if it is true -- I dislike the implications.
Though I will have to trust your experience when it comes to communicating with them. The one 'god' I am familiar with may have fancied themselves as incomprehensible, but by keeping them apart and above humanity only served to be their downfall. They didn't care for the people they communed with, the people that worked to make their god's will real. I fear that the same could be said here.
ff16 spoilers just in case.
