How about corrosion resistant enclosure? And even it will be damaged (probability is probably low) you can have a sensor to detect that and replace the enclosure. Batteries burning underground should be less a concern compared to them burning on a wood wall of a house. In case of an incident circuit breaker will turn them off, and batteries will burn themself w/o damaging anything else.

We have metal pipes underground for 10+years. Can't powerwall handle that? Also you probably don't need full enclosure to be metal, can be some corrosion resistant material, and only metal heatsink.

I wonder why don't installers put those batteries underground? If you have a front/back yard is it safer just to borrow a battery there?

That requires 110k$ and you can't just take money with that rate, it's margin. So you should have more than 110k$ to take some of that money and replace them with margin.
