Here is an option: Don't just make it fully random, but tweak it a bit in the players favor. How much is of course subjective, but for example if you have a cow and a baby you could increase the chance that they spawn next to each other. Or if you know that it's generally required to get a farmer early on, make sure you'll always have a farmer as an option in the first three rounds. Or unlock new tile types as the game progresses, e.g. ravens arent useful until turn 7 or so when the pest starts appearing, so you can think about not giving the players ravens at the beginning.
Additionally (or alternatively) you could think about letting the player adjust (some) tile placements before the round starts, maybe for a fee.
Or maybe they can somehow adjust their chances for specific tiles generally or next turn.
Plenty of ideas, which one fits your idea and your game is of course for you to figure out :D
