Seen some folks suggest Hamas deserves critical support because they're the lesser of two evils by fighting imperialist/colonialist/western powers. Obviously a controversial take for many, though it doesn't attribute Hamas as left wing. (Maybe relatively in the plainest sense imaginable?)

Otherwise I have also seen discussion on organizations like the PFLP apparently also fighting in Gaza right now: effectively(?) allied with Hamas. Understandably this works out to them being seen as supporting, if not a part of, Hamas. (Note: I am not sure of evidence of either coordination or fighting between them alike.)

I haven't seen any calling Hamas as itself left wing, though. Maybe I can see how someone could interpret the above as furthering some leftist theory, or think that's the argument at work?
