Not "pumping" losses, no. There is no intake air or exhaust gas to pump.
EVs may experience an effect that is similar in practice, albeit much smaller... Things like headlights, HVAC, entertainment systems, etc., will draw more power the longer it takes you to get to your destination, so reducing your speed from 30 to 15 MPH might not be an efficiency win.

No- those losses (less the engine idle speed) are relatively larger for electric, because alternator loss is already baked into the efficiency for ice engines.
