A lot of bots, including mine, are coded to interact in the third person. This gives your story more depth and can allow for details, thoughts and events that are outside the scope of the first person point of view. You can drive the story by adding events that are happening elsewhere, the inner thoughts of side-characters and situational context.
For example: you want an assassin to come in and make an attempt on the king's life so you can save him. Your persona wouldn't have any knowledge of an assassin picking the lock of the servant’s entrance outside the castle. Third person POV allows you to insert them into the story without possibly confusing the bot into thinking you’re the assassin or that you're located outside with them.
Third person POV also helps with the notorious problem of characters talking/acting for you. If you're both using the first person POV, then it's a lot easier for the charcter to assume that the actions and thoughts of 'I' are all fair game.
