I just had diagnostics run on my 2011 Chevy Impala to see why the traction control is kicking on mostly when I turn left. The mechanic says the sensor is sensing random movement in the left front tire even when the tire is completely still. He used a scope and determined there is nothing wrong with the wheel bearing, but recommended I replace the wheel bearing anyway. Can you explain to me why I need to replace a part that is perfectly fine instead of fixing the sensor that is not functioning properly?

The bearing might be fine, but most likely the sensor ring is the issue which is part of the Hub/bearing assembly. That would mean you would need to replace the Hub/bearing assembly if the issue isn't the sensor or wiring itself. The part is around $100.
