I'm so sorry for your loss. That's tragic.
Yes, my insurance agent (State Farm) told me pretty matter-of-factly that these days, if any airbag deploys in a crash it's usually written off as a Total by insurance. That's usually because the force needed to set off the airbag is usually enough to cause enough major damage that it's not worth a body shop fixing it, and also that the cost to replace parts like the airbags are currently through the roof.
