action groups and the kal-1000 controller

how to use action groups and the kal-1000 controller to constantly adjust the the thrust from an engine so the center of thrust stays aligned with the center of mass

There is no way in the stock game to feed data into KAL controllers and have them output as a result.

If you want to have it do it automatically, you can have a KAL control that adjusts the thrust limiter of an engine over time to compensate for fuel use and I believe you can then use a KAL controller attached to throttle to control the speed of the first KAL controller so it changes the thrust limiter at the correct rate of fuel drain in proportion to thrust. This is really overcomplicated and probably unreliable way to do it.

Depending on what you're doing, it might be easier to use a KAL controller attached to pitch/yaw controls that adjust the thrust limiter of engines to induce a thrust vector effect.
