The current odds for the CL winner:

Liverpool are top favourites which isn't a big surprise.

I didn't expect PSG to go to the top in only one year according to bookies. But they are once again a serious favourite with this game surely.
Real Madrid come as the 2nd... Maybe this can be criticized as they have a brand new manager now. But I hope Xabi Alonso won't show a bad performance in his first year.
PSG come as the 3rd which is also okay. Some websites are even showing PSG - Arsenal in equal odds.

Liverpool having the least odd is deserving, they have all it takes to win the Champions League next season because they now have a more concrete and well crafted team by Arne Slot so their hopes are high against next season's Champions League games.
Real Madrid is the giant of the Champions League and even if they didn't win the Champions League next season, they will still keep having a fair odd by the bookies and will continue to stand out in their ratings against other clubs in the Champions League, their odd being the second favorite after Liverpool is not in doubt.
PSG doesn't deserve the third favorite odd of the bookies because regardless of their outstanding performance last season, it is not enough to put them ahead of some Champions League teams who have been very relevant in the Champions League games over the seasons. Either Barcelona or Manchester City should have been placed ahead of PSG. Those websites that are giving Arsenal and PSG equal odds to win the Champions League just did that based on their own assumption and not based on reality, PSG has more possibility of winning the Champions League again than Arsenal.
I don't believe in bookies odds especially, when the competition have not started, because there are some factors that can affect the performance of these clubs next season. This was how the bookies gave Madrid the odd of them being the favorite to win this past one, that was lifted up by PSG. I didn't see PSG on this list. Maybe, PSG is in the list of other casinos.
