I guess for me the thing that tips the scales between ‘real healer’ and ‘minion pretending to be a healer’ is that I don’t think it’s actually in Quirrell’s interests to deprogram Bellatrix of her loyalty to Voldemort.
Though presumably she is at least competent in regular healing, of the sort needed to get Bella back in fighting trim.
