Korra says it herself, "Your weapon tore a link between the spirit world and overworld."Yes, she did create it. Do you think Kuvira's weapon would have just created the portal itself? The weapon was firing spirit energy all over the place, and would have continued to do so until the weapon either exploded, releasing all the energy at once in a giant explosion, destroying republic city and likely much of the surrounding area, or until the spirit vines ran out of energy, which likely would have been a while, given the vast amount of vines all over the city. Instead, Korra entered the Avatar State, and used energybending to bend the energy and drew it towards her, and following the law of conservation of energy, the energy was changed and converted into a new spirit portal, rather than destroyed. Think of it as lightning redirection; instead of the energy from the spirit vines being directed into a large beam of energy or explosion via the weapon, it was bended (or redirected) by the Avatar into a different form of release, the spirit portal. Also, consider the fact that Vaatu was stated to have created the original spirit portals. So, logically, it would make sense that the Avatar, by using Raava's energy via the Avatar State, would be able to accomplish a similar feat, given enough spirit energy.
