Likely, they couldn't since common angelic weaknesses doesn't necessarily apply on archangels. At least Lucifer just erased enochian sigils and holy fire with his mind. Also, if it is that easy to block their power, the Darkness could have also blocked their power during the pre big bang war - so it can't be that easy to block an archangels power. Whether Leviathan can kill archangels is another question.
