Hi good question. So 99% of scripts on osbot use something called Webwalker. It is basically an AI that finds the easiest routes to walk. Since teleporting to Varrock is "closer" to a bank than teleporting to Varrock, it does this. Now if you don't have any varrock teleports on you, it can't do this. I believe the script withdraws a Falador teleport automatically so just don't use Varrock teleports and it can't teleport you there. Any script with an AIO though has to use webwalker because scripters cannot write paths for such a large script
