The game is terminated when the command to hold the item off-hand of pillager is executed.

/replaceitem entity @e[type=pillager] slot.weapon.offhand 0 arrow 5

If you put a skull on the head of pillager, it will appear floating.

/replaceitem entity @e[type=pillager] slot.armor.head 0 skull 1 1

Even if the weapons possessed by pillager, skeleton, stray and drowned are erased, they will attack with arrows and tridents over long distances without attacking them.
