I don't think it's all of them, but some new models do seem to lurch.
That's probably a sign of the immaturity of some drivetrains, rather than
anything intrinsic.

I've not noticed this on buses, perhaps it's only some models on some
routes. But at any rate, it doesn't happen in hybrid cars so you woulda
thunk it was a Solved Problem.

Probably more likely to be the drivers - a lot of london bus drivers seem to
only use 2 throttle positions , zero and maximum. Ditto the brake.

Yes, but the same drivers also drove the previous non-lurching diesel
buses. Some of the new hybrid buses seem to have more sensitive
throttles.

It may be because electric motors have more starting torque. For
example, even quite humble city BEVs have very good acceleration from
zero to about 20mph.
