Would be nice to know if there is an actual mechanic behind this event, but so far from what I have seen it is purely chance as you get to higher leagues. This is what I tried to do during each league:

Rookie - Brave Bonus above 1.0 completely prevented that for me.

Summoner - Brave Bonus above 1.80 prevented most of the opponent striking first events, but I would advise to stay at the 2.50 for more points and less chance of that random occurance of your opponent striking first unless you need an extra unit for certain fights.

Legendary - Brave Bonus at 2.50 which is maxed and still have issues with my opponent striking first, basically this is the RNG league where it feels as though there's a 10-20% chance of who gets to go first at the highest brave bonus. The rage is real in this league since you must have several good team combinations to advance far or get really lucky.
