IKB asked D.J. MacHale:

I don’t think I have found the answer to that particularly but why did you chose “Halla”, was it Viking related ? Also, as it is “Allah” in reverse which is God in Arabic, to me I’ve always seen it as something related to some kind of spirituality. As if the goal was to preserve a certain way of life, a belief, to get to a sort of heaven…I may be totally wrong though haha

D.J. MacHale The answer is much simpler, and less interesting than your theories. Halla is everything. Every time, every place, every person that ever existed still exists in the sea of time and space. So I used simple root-word to come up with the name: all.
