Any sportbooks/casino without KYC ?
Most of the crypto casino don't require initial KYC upon registration except for those accepting fiat deposit. You will only just required to undergo KYC if your has been involved on shady activities or in simple terms you violate the Casino ToS. I suggest playing on Web 3.0 Casino if you really want to avoid KYC as much as possible since you don't need to create account there and you just need to connect your metamask in able to play. Betfury and Owl.games are known Web 3.0 casino that offers sports betting.
I'm afraid you still cannot fully avoid KYC even if you play on Web 3.0 casinos and sportsbooks. Lest we forget, these casinos are not decentralized. These are centralized casinos. Interested players are still required to create accounts on the site if they wish to play.
As to the two casinos that you mentioned, Betfury has this in its terms and conditions:
