What about Lagrange points? If the JWST can focus on a target millions of LY away, surely a few giant mirrors could focus on a reasonably small section of earth.

Even if they could, the L1 point would be directly centered between the Sun and Earth on the already illuminated side of the planet, which is obviously not helpful. The L2 point would be on the other side of the Earth, on its dark side, and completely within its shadow so also not helpful.
From the L4/L5 points you would not only be rather far away but also only able to hit areas pretty close to the dusk line anyhow.
