Because they're not liable for any of the outcomes, either individually or in aggregate. I don't believe the govt is generally liable for these damages as long as there was a genuine purpose to it.

I'm starting to think that the modern, loose usage of SWAT is cruel and unusual punishment without a proper conviction. The punishment for actually stealing the air pods is likely less than the trauma of being SWATed and the fines are likely less than it cost to replace windows/doors/whatever.
