Giving Pillagers, Illusioners, and Piglins weapons using commands

If you use commands to give a Pillager a sword, it will be shown in the Pillager's hand. However, the Pillager won't use it to attack the player because they're basically passive if they don't have a crossbow. Additionally, they can't use bows either. Pillagers should attack the player with or without a weapon.

Illusioners also become passive if they don't have a bow. They can't use swords, or crossbows. The sword part is understandable, but they should be able to use crossbows if they have them (I know they're unused mobs, but still).

Piglins can't use bows. I think they should be able to. I've also tried putting firework rockets in their offhand, but they simply put them in their inventory instead of actually using them. Piglins should use whatever ammo is in their offhand instead of putting them away (similar to how they can still hold shields).
