Two questions. How can I make my mob explode and how cam I make my kib immune to explosions?

Yeah

For the first one, use the minecraft:explode component.

For the second one, use a damage sensor like this one:

"minecraft:damage_sensor": {
  "triggers": [
    {
      "cause": "entity_explosion",
      "deals_damage": "no"
    },
    {
      "cause": "block_explosion",
      "deals_damage": "no"
    }
}```

This will make the mob not take damage from explosions
