I think Evenepoel is actually still the leader and rightly so, but...
1. Evenepoel should be the leader in all hilly one-day races. He should be a co-leader for the Tour and in any one-week WT stage he contest. But always with a joint-leader because he fails too often in the mountains.
2. Lipowitz should be the main leader for the Tour, with Evenepoel as a co-leader. Lipowitz should also target the one-week stage races, but besides the real mountainous ones, is not a very good choice for actually captaincy.
3. Pellizzari, should have a completely separate program from Evenepoel and Lipowitz in the first half year, and potentially some shared duty with Evenepoel only after the Tour. Should be a leader everywhere he starts, but he still needs to learn actual leader skills as he seems way to nice at the moment.
4. Roglic, should be a co-leader when he starts and can start some races together with Evenepoel or Pellizzari. He shouldn't be the single leader anymore in my opinion, just shared.
5. Hindley, still deserves a well-balanced program with some leadership or co-leadership roles and some domestique duties in my opinion. Then let the road decide how long he can stay in that role.
6. Van Gils, same as Hindley but for the hilly races.
7. DFM, mostly domestique nowadays in my opinion and a good one at that when in shape.
8. Vlasov, should be a domestique mostly, but is a very bad one unfortunately. I would let him leave after this season.
Others are even lower in the hierarchy or are skilled in race types where Bora can just allow them their freedom and see what comes out of it.
