#1 AJ Styles and the Club cheat in order to win
As we have witnessed on the last two episodes of RAW, The Club isn't shy about having all its members attack one guy. They've interfered in matches before and won't stop that tactic any time soon. While it would kill any momentum that Ricochet has established, an easy way for Styles to grab another US Championship would be to have him win with a little help from his friends.
If WWE wants us to take the recreated partnership seriously, then they all need to be holding championships. While the US Championship is only the secondary belt on RAW, it is still a title and immediately increases a performer's stock. The Club will most definitely be at ringside and if they are in Styles' corner, then they aren't going to be there to look bald and pretty.

I think the question is not if they will interfere but how much Gallows and Anderson will interfere. They might get caught by the ref and sent to the back or they could pull off some successful shenanigans that would see their leader win another title.
If this reformation of The Club was only done to have the Good Brothers resign, then they'll go back to being jobbers again before we know it. Having a title or titles to carry around would give the group some clout to brag about.
