Companies should be on the hook for this because what their employees say matters. I think it should be entirely enforceable because it would significantly reduce manipulation in the marketplace (IE, how many times have you been promised something by an employee only for it not to be the case? That should be illegal)
This would have second order effects of forcing companies to promote more transparency and honesty in discussion, or at least train employees about what the lines are and what they shouldn't say, which induces its own kind of accuracy
