That is incorrect. They always affect fueling. The OL provides an offset that can be used to reach target AFR. If your AFR target is richer than you want, adjust the AFR target table. The OL fuel table will allow you to adjust fuel trims (and initial onset fueling).
I was super rich when I got the flash and changed my OL cells (in the MAP, not global) to be in be 40's.
