I think you are mistaking the map for the territory. I think you are blaming the data (actual usage) when the model is wrong (dictionaries). "Literally" is allowed to have a valid and true definition of "figuratively" because exaggeration and hyperbole are used for rhetoric and expression. That's a vital and popular way language is used, and in the case of "literally" it is so commonly encountered that it worth noting in descriptive texts that it's common.
