Seems to me that "voronoi" is not what you are looking for. Maybe you could have a look at some of the topographic modules like r.param.scale or the addon r.geomorphon to extract the valleys. Or you could you r.watershed but output the streams and/or the accumulation map to identify the valleys. Then some magic to reduce these to lines (r.reclass + r.thin maybe).
