It seems to me that the 9 points that Roma has will be enough to qualify for the preliminary playoffs. It is unlikely that with two rounds left in the group tournament, the entire group of teams that are currently at the bottom will score from 4 to 6 points. But of course Roma is not in the group of favorites of the tournament because their game and results are terrible. And by the way in Serie A they are really close to relegation.
If you count the remaining matches, it might be true because it is difficult for the team below them to get 4 to 6 points in the remaining two matches so that Roma's chances are much greater. But to ensure this opportunity, Roma must take advantage of the two remaining matches so that they can qualify for the play-offs without having to wait for the results of the teams below them. Roma is indeed not favored this season because of their inconsistent performance and even for the competition in Serie-A Roma has performed very badly with conditions like you said.
Another additional question: does Roma need the Europa League? Why do they need 2-4 extra matches there if they have no chance of winning the title? They have more important tasks in Serie A - they are currently just two points from the relegation zone. There is a potentially easy game against Parma, but then Milan, Lazio, Bologna. If I were them, I would be more worried about that.
Roma's hopes in Serie A are just trying not to be relegated, they are certainly capable of that. because chasing the top 5 positions in the standings will also be difficult for Roma, Roma's performance this season cannot be favored in Serie A. Still, maybe they will definitely try not to be eliminated in this qualifying phase. even through the playoffs, there is a possibility that Roma will also meet a strong team and will have difficulty qualifying.
