Yeah. Lagrange points are a characteristic of two-body systems. While you'd get areas of increasing stability if a cloud condensed into two bodies, the rotational motion of the stuff in the cloud would outweigh that, and more stuff would be pulled in by the more massive bodies anyway.
If you got really lucky you might end up with a little bit of dust that happened to be going slow enough, but it's still not going to stay there. Solar wind is going to push stuff around, and to stay at a Lagrange point takes active adjusting. It's not a low point in gravity, it's more like balancing on the peak between the two bodies.
I thought that was true of L1, L2, and L3, but not L4 or L5—hence the stable clusters of trojans at Jupiter’s L4 and L5 points.
Correct from what I can see. L4/5 are stable
