No one called airsoft games "tournaments"; that's a paintball term fyi.
Some established fields do have insurance, however most rely on a waiver system. Between the waivers and a general understanding that everyone involved is assuming some risk when playing, I have not heard of any problems in 13 years of playing the sport.
I've sustained broken ribs and a lacerated kidney playing, and I didn't go after the field owner...etc.
