Because the live wire has a negative voltage half of the time, that must mean current is flowing to the live wire from ground, right?

Current flow in AC is to and from the live and neutral all the time. Half from neutral and half from live. Ground is there for safety for a ground leak trip device like in your house, that when u touch live or neutral and u are grounded say through bare feet the shock is only momentary and then the trip switch should have opened.

Yes, it is flowing from the neutral wire to the live wire half of the time. It switches directions 60 times a second. Think of electrical charge in a wire like a belt around pulleys, but in the case of AC, the belt is moving back and forth instead of continuously.

Not from the ground wire, just from neutral.
The neutral is often grounded at the feed point to the building.
