No. Higher _quality_ printouts, e.g. on Photo paper, use more ink. On the same media, lower resolutions just use fewer but larger dots, effectively giving the same ink saturation, only more jagged.
If you're so concerned about ink cost, and your Epson is acting up anyway, then maybe it's time to move on and get a Canon.

I'm assuming LED means printing above whatever DPI is needed for the pic's resolution to produce photo quality wouldn't give you much better results, but printing anywhere under that DPI, you'd notice a better picture as you increased the DPI.

Eco mode is not using a lower resolution, it's just making smaller and/or fewer dots, producing lighter output, not coarser.
