Let’s assume bots are real, and can play perfect equilibrium poker. Profitable poker games might necessarily fill up with bots, that can then collude both as nodes and on the table. Then much of the real world bitcoin economics applies, as to the risk/rewards/costs of creating bots and bot rings.
IF these bots/nodes can be put in a decentralized equilibrium AND they could also create/maintain private games…then players could pay rake to this lower level bot infested ring, in order that they may organize and create their own intended poker game (or variants of :)).
This way bots have incentive to hold up the network AND to be honest as a jury pool. Players are free to create their own games and fields, provided they pay the necessary market equilibrium costs.
