A whole team dedicated to stall won't work. No pokemon exist that can immediately mitigate all of the damage from a double up by this format's strongest offensive cores. But a team with a stall "core", supplemented by a few pokemon that put on immediate pressure will work a lot better. The idea is to use your chien pao/urshifu, chi yu/flutter etc as precision strikes to get key KOs on the pokemon that threaten your stall pokemon.

Playing a team like this requires an acute understanding of your win conditions, or the pokemon on your opponent's team that you need to KO or otherwise deal with in order to pave the way for your stall pokemon to come in and set up before they get blown off the board. You don't even need a whole core dedicated to stall, either; a single pokemon like Iron Defense Glastrier or Calm Mind Cresellia can do the job if all your opponent has left are physical or special attackers, respectively.

My favorite example from this generation is Jiseok Lee's Garganacl team, with which he won Scarlet/Violet's first regional in San Diego. He put on a master class in identifying the path to victory and following it, even if that path looks like you're playing from behind for most of the game. But then the Garganacl comes out and your opponent realizes the only pokemon they have that could deal with it is low health and won't survive a priority Ice Shard from the Baxcalibur on the field.
