This is because the US was doing something that was already
inherently an act of war. Overflying someone's sovereign territory
without their permission is an act of war. The only reason why
it didn't start a war was because the Russians didn't feel like
starting a war over it.
Of course, the US isn't above contriving a trumped up situation
where someone shoots at our stuff to start a war. However, the
US habit is to do this with our stuff in/over international waters.
It'd just be plain embarrasing to try and start a war over the
shooting down of an unauthorized overflight.
With space, the precedent has already been set that outer
space is international airspace. When Sputnik flew, it opened
the door for US spy satellites to orbit over Russia with
impunity. If the Russians can overfly in orbit without asking
any of the hundreds of overflown countries for permission,
so can we.

True enough. The precedent set today could be changed by
future cultural changes and/or specific political developments.

Unfortunately, hunter-killer drones will need a LOT of delta-v,
compared to a simple sensor drone.
A sensor drone only needs enough delta-v to get boosted out
into interplanetary space. Without braking fuel, this drone will
eventually drift out beyond useful range, but this could take decades.
A decades old sensor drone is going to be obsolete and you'll
want to retire it anyway. So you'll be launching replacement
drones anyway.
A hunter-killer drone needs enough delta-v to get boosted
out, and then braking fuel to get on station, and then more
fuel to intercept a sensor drone. It also needs sensors
of its own to home in on the target. All in all, such a
hunter-killer drone could be much more expensive than the
target it's meant to kill.
(I don't call them "satellites" because they aren't in orbit
around a planetary body.)

Or you could get something like the real world history of
spy satellites, where attacking satellites is expensive and
difficult (so far). And attacking them is considered an
act of war because they're considered to be flying in
international airspace.
