I have a set of points in 2D generated by doing a DimensionReduce on a list of colors:
colors = RandomColor[100];
coords = DimensionReduce[colors, 2, Method -> "TSNE"];
ListPlot[Thread[Style[coords, colors, PointSize -> .05]]]
However, I would like to arrange these points into a regular 2D grid (or other lattice) while maintaining neighbourhoods as much as possible.
Is there a function to provide this transformation? Or am I better off writing something to shuffle the colors in a grid to minimise neighbor distances?

It is hard to understand what you mean, but here is a simple take. Round can take an arbitrary step. That makes a grid of an arbitrary step.
colors=RandomColor[100];
coords=DimensionReduce[colors,2,Method->"TSNE"];
gridStep=.5;
ListPlot[
Thread[Style[Round[coords,gridStep],colors]],
PlotStyle->PointSize[.03],
Frame->True,
FrameTicks->Range[-10,10,gridStep],Range[-10,10,gridStep],
GridLines->Range[-10,10,gridStep],Range[-10,10,gridStep],
GridLinesStyle->Directive[Gray, Dashed]]
