See, if that were the case her goal is really noble, because to have considered a time paradox in trying to prevent the first spacequake from happening and factoring it in her plans... not many in her shoes would have thought it through this thoroughly. There is another possibility however, and that is Kurumi actually being afraid of forming any sort of attachment to the world, since it would mean she would not be able to follow through her plan, and not having to consider any personal feelings or potentially conflicting decisions in trying to kill the First Spirit.

From what Kurumi's doing, killing off the first Spirit will apparently prevent the other Spirits from coming into existence (causing a grandfather paradox; though if this is a stable time loop then it's implied that she failed), though we don't know how. So unless Phantom turns out to be the first Spirit, killing the first Spirit would still enable Phantom to do its thing.

This is dependent on the fact that if there are alternate timelines which still have Spirits crossing over to the present world from their dimension, irrespective of whether the first spacequake actually happens or the First Spirit actually causes it. Kurumi might fail in that instance, regardless of whether she is successful in her goal.

Apart from this, we have not a clue as to whether the Phantom is a Spirit or simply an entity from the other dimension that governs Spirit powers. This is a plot point that hasn't been covered, but hopefully it will in the next couple of volumes, or possibly when all ten Spirits have finally made an appearance.

Here's the interesting thing about spacequakes in this series thus far: the first one that is caused brings over the Spirits from their own dimension. With Kurumi and Kotori it's been proven that the Spirits can cause spacequakes out of their own accord, independent of the first one that is caused (which is the one they have no control over).
