Spoilers

To clarify the RvB thing, they made a digital imprint of the Director's mind to make the Alpha AI. Tex came along as a biproduct because the Director's memory (obsession) of Alison, his late wife, was so strong. Over time, the Alpha, its fragments, and Tex began to develop on their own. Carolina just uses AIs to help her.

P.H.I.L.S.S. also seemed pretty human, but she was copied, which (I don't think) you can do with an advanced AI if you're using Halo logic. Same with Freckles.
