No, it requires declaring a blockade, then it would be on Venezuela to declare war or seek UN aid. If the UNSC approves the blockade, then Venezuela is on their own. If the UNSC does not approve, they can seek a resolution from the UN the General Assembly, which the US can veto. They are thus back to square one, and can make war and seek allies in a bilateral fashion.
They likely realize that would go poorly for them, and so they are doing as they are doing and complaining and nothing more.
