As per the epic Drupad was their father, just as Kunti/Madri were the mother of Pandavas+Karna. So obviously there would be no other father of Dhristhdhyum/Draupadi.
As per the epic, Pandavas had two fathers, Pandu and the supposed god who did the Niyog, so they are called as the sons of Pandu as well as sons of the said god(Karna as son of Adhirath/Radha and Sun), as per the epic Draupadi and Dhristhdhyum were born from sacrificeal Firestand (Yagyavedi) so they are called Yagyaseni as it was the origin. As per the epic they had no other parent(neither biological nor adoptive nor legal), so obviously they will only be called children of Drupad.
However just as we know that the Pandavas+Karna were not the children of gods, we know that Draupadi n Dhristhdhyum couldn't be from the Yagyavedi, Pandavas and Karna had some biological father about whom we don't know because epic never says that they weren't the children of gods, similarly Draupadi n Dhristhdhyum had biological parents about whom we have no clue about since epic never admits they had one, they had simply popped out of the Vedi once.
Vyas didn't say about Ekanamsa being Draupadi(if she was the one) for the same respect he didn't tell us the. Name of biological dad.
Rest obviously this can't be said to be a 100% correct fact, it's just an assumption, basis SB n HVP. And the fact that Krishna was so close to Draupadi and Drupad before Swayamwar (so as to even give dowry for her), although he wasn't so earlier, because he never approached Panchal for support against Jarasangh
