How would we detect a rogue black hole on route towards our solar system?

We wouldn't. Even a small neutron star would be too dim to detect until it was already in our solar system.

Unironically small black holes are really bright.

What like there's stuff falling into them? Why would they be bright?

Not really? Unless by small you mean less mass than an asteroid. And we don't even know if black holes like that exist.

There's no fucking way we'd see it that way. The sky is huge, we'd notice the gravitational effects if at all and by then it's already far into the solar system.

But visible(angular) lensing would come from large(diameter) [[Sun mass bh is 3 km]] bh, who in turn would greatly affect surrounding stars because of its mass.

What is a rogue black hole? Remnant of primordials moving at intergalactic speeds.? Dead masive star that has its orbital path intersect ours.? Something formed and kicked from the center.? How massive is a concern?

Man how has no one answered you correctly? The ealiest way to detect it would be it altering the orbits of the heavenly bodies in our vicinity.
