As I recall, neither of our galaxy's jets are pointing near the solar system. And we're distant, and relatively well shielded. So I doubt that there could be any danger.
If you were on axis, though, anything "in" the galaxy would be at risk. Given that we see jets in other galaxies that are longer than their radii.
3C 273's visible jet is "~200 kly (60 kpc) long".[0] There's even a Hubble image.[1] Our galaxy is about 150-200 kly in diameter.[2] And the Large Magellanic Cloud is ~163 kly away.[3] So yeah.
Now, seriously, what would be a safe distance for an Earth like planet to be from such an unlucky event?
