Raguel was not too kind and his purpose in helping Lucifer to stop the mess was because the light camp was at a huge disadvantage due to the location of the time and space storm.
The demon's side could just run away, but the angels couldn't run away so easily because it was their domain that collapsed.
Fortunately or unfortunately, the demons were trapped at the center of the storm with so many other battle angels, which was why the demon lords helped out.
The center of the storm was naturally the safest place, but this was not long-term safety, and the group also had to stop the storm or escape before the storm became bigger.
Ainsley, as a part of the mid-level world's citizens, had a selfish intention to stop the storm because if the storm was not stopped, it would affect the mid-level world and might also affect the Sloan Family.
If she had the capability to stop the storm, why not?
But it was easier to speak than to do it.
