The menu for picking your team as a whole (the same menu that you pick music from) in linked battles has no timer. both parties must finish picking their teams and confirming before the next menu appears, so if you've finished picking your stuff and your opponent hasn't, you must wait until they do with no ability to back out.
This is unlike ranked battles where the menu is essentially a waiting room before an opponent is chosen.
tl;dr ranked battles and link battles work differently, and link battles has an exploit for softlocking, while ranked doesn't.
