LT does not find errors for the determiners tous/toutes (all). "tous" is for males words, while "toutes" is for female words. E.g. "Tous les hommes" (all the men) and "toutes les femmes" (all the women), "tous ces hommes" (all these men) and "toutes ces femmes" (all these women). I suppose this is because the following article (les) or adjective (ces) is gender neutral. In the singular errors are found: "tout le chien" (the whole dog) or "toute la femme" (the whole woman).
