I suspect they may have a common source of inspiration, that is, those Voodoo dolls made of straw and such. They share a common motif of faceless "woven" creatures resembling humans only in a figurative humanoid shape. And Voodoo, of course, is rooted in Louisiana.
But I wouldn't be surprised if the developers were genuinely inspired by BIO7. At the beginning of the game, it had a similar True Detective-like shot that 7 utilized as well. And the rot of what is presumed to be Lovecraft's Shub-Niggurath is a vector of fungi, which is quite important for the story. But these are the only potential similarities that I've noticed.
I should add that Alone in the Dark is an amazing love letter of the classic trilogy and is a hardcore Lovecraftian fiction that is directly connected to Lovecraft's myths. If the game fails commercially, it will be a great shame, but people don't care about old-school horror these days, so it's expected.
