I don't think a particle could be so energetic that it couldn't be deflected by any magnetic field - the particle would have to be infinitely energetic in that case - but perhaps they meant 'any plausible astrophsyical magnetic field source that we know of'.
Yeah obviously not completely unaffected, what they're saying is that the deflection by anything that they know of that could feasibly be involved here would be negligible.
Below is a quote from the Guardian. Apparently the particle has been named Amaterasu after a Japanese sun god if I remember rightly. The even higher energy event recorded in about 1990 was called Oh-My-God. If they find something higher yet they've already decided that it will be named Jesus Fucking Christ
particles with Oh-My-God or Amaterasu-level energy would be expected to blast through intergalactic space relatively unbent by galactic and extra-galactic magnetic fields, meaning it should be possible to trace their origin.
