If someone is walking down the road, is the air around them moving to avoid the person, or are they more like a knife cutting through the air?

Both. By walking through air youre pushing the air infront of you into other air. This creates a bubble of high pressure air infront of you. As you leave your stationary position, you leave a vacuum where you once were and it is quickly full of air. So some air you push and some air you pull.
