Pretty sure that the answer is no.
Depending on what the dialogue options actually do, it seems like a better idea to just randomize/compute the effect of whatever choice the AI player should be making.
Examples:
Does it spawn a unit of the player's choice? Just skip showing any dialogues to AI players and go straight to spawning them a random available option.
Does it set a variable for the player, that is to effect something later? Same jazz, just set the variable to whatever without waiting around for the AI to hypothetically click a button that never actually gets shown to an actual player anyway.
