Bobbi Kristina's family is pissed over reports that Oprah Winfrey and Tyler Perry orchestrated a Hail Mary to save BK's life ... when they had nothing to do with it.
Sources close to the Houston and Brown families tell TMZ ... it was Pat Houston -- and not O or TP -- who organized a medevac airplane to bring BK to meet with a specialist in Chicago.
We're told the family feels the report makes them seem like they're relying on celebs to take care of BK ... when that just isn't the case.
As TMZ previously reported, once the specialist told the family there was nothing to be done ... they decided to take BK off all medications and allow her to die in peace.
