What does A.I Bonus do?

[Legatus Adeodatus Iovita Manilus]

It doesn't seem to work for me, It doesn't change enemy morale and it doesn't seem to make the campaign any harder.

apparently it is sometimes bugged and will not work unless you go into the game files and change settings. I unfortunately do not know how to do this.

AI bonus has following effects:
-campaign: more recruits for AI
-battle: AI units inflict more casualties and will not break as easily

Does that mean that there armies are larger, or that they have larger reserves?

That they will run out of recruits later. Recruitment speed comes from difficulty level.
