Not true since only a fraction of the exaust can be used for thrust,=

Not true, all the exaust can be used for thrust if you don't tap any of it off
to power something else like the Liniac.



at a regular rocket engine. The electric system may be easly reversed

for slowing down.

Only if you make the liniac run through the ship.  Not that you need to do
reverse thrust on short notice in a starship.
