Actually, the game should make it difficult to find out whether the “AI” is really an AI or a human.
Unless the AI wants to reveal itself (a Friendly AI may wish to reveal itself to a single player, for example; or an Unfriendly AI may wish to reveal itself and pretend to be Friendly). Once revealed, the AI’s player can talk to other players, and engage in diplomacy.
