I don't know any anarchists that would refuse a Marxist-Leninist analyse (but they do exists, I'm just not organized with those). In fact this is very common in the autonomous movement (formally "operaist"); I know this is different now, but back in the days, Maoists shared a lot of point of view and actions with anarchists and autonomous, and other not with party driven Marxist-Leninist organization.

Their is a very specific marxist-leninist trend on *.ml that do not represents the diversities of those ideologies. Futhermore, their is a lot of ML comrade organizing in maxists, class-war or internationalist organisation with none ML people. Previous example ( CNT, ICL and the IWW ) have a strong strong marxists tradition. At that point, those differences seems not that big if we do try to have a revolutionary action (so a revolutionary and internal one); I agree that individualists approach are misleading. But with the rise of fascism, nationalists one seems very misleading too.
