Why does a lone pair of electrons push away bonds more than a typical atom. For example, "120 degrees" vs "less than 120 degrees"

Lone pairs have higher electron - electron repulsion and thus they take up more space than atoms, pushing the surrounding atoms closer together and lowing their bonding angle.

Yes, since lone pairs are concentrated closer to the central atom than bonding pairs.

lone pairs each have a negative charge, and they also have to respond to the charges of the atoms, making them push in the directions that they do push in. Think of it as a bunch of magnets of identical charges.
