I think forced draws (in the manner of perpetual check) in tablut are nonsense. A voluntary draw in which both sides willingly repeat position indicates a mutual desire to draw, neither side thinks that they can win but in tablut white, in an otherwise lost situation, can force a repitition to avoid losing. The fact that this can be done in chess has no bearing on the situation in tablut. On the tablut rules page there's a statistic that at BrainKing white has won 60% of the games, this is already a large enough advantage without adding the extra resource of being able to force a draw (black can not force a draw). For black avoiding a draw is as big a challenge as is trying to win. I dont know if it would help to remove the draw as it might make it too easy for black to win but as the present situation is unfair I suggest that games that end with white forcing repetition shouldn't count as a result but instead should be replayed with the colours reversed.
