Its been ages since I played NWN1+2. I can tell AoO happened automatically but I am not sure if you could have more than one.
In Pathfinder Kingmaker there is a feat that allows you to have more than one AoO per round. (combat relexes). WotR has it too, plus a mystic feat to get more AoO. It makes sense to use this feat: - When standing close to an archer you get an AoO for every shot they make unless they have a feat to avoid this. - Several of your chars have outflank and/or seize the moment. When somebody makes a crit against an enemy, all other chars get an AoO against that enemy. If the AoO is a crit it can lead to a long chain of attacks. Should the enemy still be alive after this, the next char can get a crit with the regular attack, starting a new crit chain.
I'm presuming NwN 1 had Improved AoO feat which let you do 1 AoO per person leaving your square. But my knowledge of the feat comes from 3.5 and that would be NwN 2 since NwN 1 was 3.0
oop maybe it was called combat reflexes.
Edit* Ya it is, didn't bother getting the actual books, found it here: dandwiki NwN 1 doesn't have this feat but has two feats to get away from AoO.

Range You can make ranged attacks only against targets within a specified range. If a ranged attack, such as one made with a spell, has a single range, you can’t attack a target beyond this range. Some ranged attacks, such as those made with a longbow or a shortbow, have two ranges. The smaller number is the normal range, and the larger number is the long range. Your attack roll has disadvantage when your target is beyond normal range, and you can’t attack a target beyond the long range.
Ranged Attacks in Close Combat Aiming a ranged attack is more difficult when a foe is next to you. When you make a ranged attack with a weapon, a spell, or some other means, you have disadvantage on the attack roll if you are within 5 feet of a hostile creature who can see you and who isn’t incapacitated.
Reaction Page 73 Certain special abilities, spells, and situations allow you to take a special action called a reaction. A reaction is an instant response to a trigger of some kind, which can occur on your turn or on someone else’s. The opportunity attack, described later in this chapter, is the most common type of reaction. When you take a reaction, you can’t take another one until the start of your next turn. If the reaction interrupts another creature’s turn, that creature can continue its turn right after the reaction.
