Probably because Nitrogen is more expensive.

Most likely. And actually humane gases would be rarer and more dangerous to ... well, humans working there.

CO^2 is The gas that causes panic since that's what the body uses to regulate it's oxygen/carbon cycle. It's a built in alarm. Plus you can just vent it to atmosphere. And it's cheap.

CO2 is also denser than air, which means it stays in the "pit" the animals get lowered into.

I'd think you could build some machine to (re)harvest nitrogen from the air and it would eventually be free. But maybe that doesn't exist / super hard to do...

Or you could just run a pipe from the building's furnace or generator exhaust to the pig-gassing room and use the CO2 your facility is already generating.
