No, but liberalism the ideology explicitly rejects corporatism. Neither the DNC or GOP have 1 ideology, but I think it's fair to say, every major DNC candidate at least since Gore has been corporatist.
Liberalization of the economy directly led to what you call corporatism
Maybe to some extent, but an illiberal economy still has a lot of corporatism. See Transnistria lol. And, in a perfectly liberal economy(which admittedly will never exist) there could be no corporatism, as there would be no state power for corporations to wield. In a less perfect world, a limited state, such as by strong constitution, limits the possibility of corporate abuse.
