How does the US get to 240v if you guys don’t have multiple phases at home?

Not an electrician, but here In Europe we get to 400v by combining the three 240v phases we get.

US power is really 240V with a neutral. It’s wired to most outlets and circuits as one 120V leg (against the neutral). But you can absolutely wire a 240V circuit using both legs and major appliances (air conditioners/heat pumps, electric driers) use 240V. My Tesla charger is on a 240V 60A circuit.

We don't have three phase but power coming into most panels in the United States has two 120V lines that are 180 degrees out of phase so that's enough to construct the 240.
