Why don't we launch a probe axially out of the solar system instead of always radially? Wouldn't we reach interstellar space relatively quickly?

Probes often use the gravity of other bodies in space, like moons or planets, to slingshot faster out of the system by falling toward them, sorta. The acceleration from Earth axially out of the system would have to be all of its own power.
