I suppose, in theory anyway, that AI, presuming that it self learns, will look at religion, and assuming a scientific MO, would take the view that without evidence they are all simply beliefs. What AI might not understand is such global conflict arising from such arguably simple beliefs. One AI would probably process such contradictions internally, but what if two AIs start chatting?
The law as it stands will only complicate matters because to have varied and non compatible laws globally nakes no sense whatsoever. Humanity isn't logical, and so what this comes down to in the end, is how a super intelligent AI deals with such chaos, and from what base agenda. Whether or nor AI choses to interfere, just observe, take sides....nobody knows.
