A throttle is excellent on an e-bike especially for city riding. It is far easier to move at slow speeds by applying a small amount of throttle vs. trying to torque the pedals just the right amount, if behind someone or near pedestrians.

Many e-bikes don't have torque sensors and instead use a cheap rotation sensor so the motor engages almost randomly at certain points in pedal rotation when moving at slow speed.

Today, those are mostly limited to Walmart-tier quality e-bikes. Even the very next step up (still big box store bikes) usually come with torque sensors.
