A hundred year radius sphere is not that big, about ten thousand stars in that range, and even then, only those 50 years out (a coupla thousand) would have had time to return a possibly malignant signal.  We can’t dismiss the Dark Forest notion yet.

True, the proposed hostile aliens might not have heard our signals
yet.  But going dark now does nothing to prevent the signals finding
them eventually.  In other words, if this is the truth, then we're
already doomed.  Alien civilizations would realize this too and, once
their earliest broadcasts had covered the vast majority of the galaxy
with no immediate hostile response, come to the conclusion that said
immediately genocidal aliens aren't out there.
