This isn’t over yet. Lochte is being charged and subject to arrest or fine in Brazil. I presume his attorneys are trying to work this out. Brazil won’t try to extradite him, but they could file a red notice with Interpol which would subject him to arrest if he leaves the US. Also, the USOC is going to decide later if there should be discipline. Lochte has really screwed up and it will probably cost him millions in lost revenue.
He could go to the Ecuador embassy for safety.
