If it's a true AI make it so it feels genuinely Wakandan. I think it would be lazy to just make it turn evil, it would be a Maberry move. Sure youcould do a story where She goes rogue, but ultimately I'd have it act as if it were a member of his Dora Milaje. Except an AI construct.
You know like Cortana. Or Data from ST:TNG. He was AI but he still chose to be who he is.
