She asks: “If for whatever reason the enemy decides to destroy us instead of leaving us alone, could we and our family members ask to leave the body without having to suffer at the hands of the enemy?”

Here you are seeing a perfect illustration of the harm in such a message being conveyed to others. It gives a false sense of reassurance there is nothing really to worry about because you can simply escape if such a terrible thing should happen and you are under attack by a powerful enemy bent on your destruction. So it is encouraging complacency in the face of danger. The reality is you will not be able to do what you are envisioning here. The only way people can escape their body is through death. Death is always self‑chosen on some level but rarely when one wants this consciously. In actuality, at the time of death itself, there is a divine protection that can be granted to minimize the suffering. That is what you can ask to have happen, but it is far better to not get in that state of peril to begin with. If you apply yourself in asking for a divine intervention to raise up your adversary so they leave you alone and unharmed and withdraw to pursue their interests elsewhere, that will keep you safe and not needing an ultimate escape from a painful threat to your safety.
