I think no. Video games traditionally give tips - these are designed to help out players who aren't sure what to do. They are not designed to be the best possible move.
If the game autoplayed the best possible moves, what would be the point of learning poker? Where would skill come into the mix?
This lawsuit seems frivolous to me. I would never expect a game to give me the most optimal hint - only a hint for how to get closer to winning.
