Llamas or trader llamas summoned through commands behave incorrectly when the EatingHaystack tag is set to 1 (true). The mob spawned appears to have no AI, though after attempting to tame it, it behaves as it normally would. When attacked, it receives knockback, unlike mobs with no AI, but continues to remain motionless. The llama behaves normally if EatingHaystack is set to 0 (false).

How to reproduce:

1. Execute the following command:

   /summon minecraft:llama ~ ~ ~ {EatingHaystack:1b}

2. Notice that the llama never moves on its own, no matter how long you wait.

Expected result:

The llama would either be unaffected by its EatingHaystack tag being set to true, or it would reset its EatingHaystack tag after a few seconds like a horse.

Observed result:

The llama remains motionless forever, until a player rides it, at which point it resets its EatingHaystack tag and becomes mobile again.
