Quinella's attempt to go into the real world is explained very late into the underworld.

The Integrity Knights have their memories stolen and turned into a crystal. Then Quinella kidnapped all of their loved ones and turned them into swords. Fusing that with the memory crystal creates the sword golem. The crystal senses it's loved ones and desires to be with them but they're just out of reach. Creating a mindless killing machine. That's an extremely simplified version of pages of expostion. It's the same process Eugeo uses with Alice's memory fragment to kill the sword golem.

As strong as the Integrity Knights are there's a very small number of them compared to the thousands of enemies they have to fight in the Dark Territory. They're not enough by themselves to win.

The minions were there to prevent anyone from climbing higher on the tower than the allowed limit. Quinella didn't want anyone to attack from the air.

Top down AI are basically the type of AI we have today. Hightly sophisticated computers, that are able to complete complex tasks, but only information they've been given access to. Yui is an example of this type of AI. She mimics humans, but put her into a situation that she does not know or is incapable or researching and she doesn't know what to do.Bottom up AI are AI that form like human beings do. They're capable of making dynamic decisions with incomplete or no information.

Rath wants an AI cable of warfare, which is why it has to be bottom up AI. They want units to be sacrificed in battle with no loss of real human life as they see it. Underworld, and Kirito's contribution were aims to that goal. They plan on wiping out all of Underworld once they get their true AI from it. Rath can't speculate in real time because of the time dilation. The simulation runs a 1000 to 5000 times the real world. It's impossible for them to view that in real time. So their ability to view events has a significant time delay.
