You can't format strings like that.

Also, use foreach for player loops.

public OnPlayerDeath(playerid, killerid, reason)
{
    if(GetPlayerWeapon(killerid) == 38)
    {
        foreach(new i: Player)
        {
            if(IsPlayerAdmin(i))
            {
                new string[110];
                
                format(string, sizeof(string), "{FF0000}%s has been reported automatically by the server[Reason: Minigun], Advice: Spec", killerid);
                SendClientMessage(i, -1, string);
            }
            else
            {
                if(IsPlayerConnected(killerid)) return SendClientMessage(i, -1, "{FF0000}WARNING: %s HAS LEFT THE SERVER", killerid);
            }
        }
    }
    return 1;
}
