I can point you to a script that is already made and working. I use it and it hasn't killed the king for my melee druid. However, there are a couple caveats.
There is NO GUARANTEE that a cow script will not kill the king if you're using some character like a chain lightning sorceress. There is a chance that it could happen, although the script does a pretty good job of avoiding. I learned this while using a ww/trap assassin. My sin had done nearly 200 runs and then accidently killed the king.
Before you deal with the above problem though, you're going to run into the problem of not having enigma. Right now, there are no bots that have a solid walking pathing script. It's just too difficult and time intensive to make a solid walking script. So without enigma.... your're going to have trouble getting the bot to clear the cow level before the script ends or the game hits me.maxgametime. It will also be very glitchy getting the leg and what not. I don't recommend it.
Lastly, I'll point you to a couple different options and let you decide. I personally would not run the bot without a tele character (unless you're doing low level botting under lvl 20), but you can try it and see what I'm talking about.
Here is an add-on script you can add to stock d2nt:

Here is a more complicated, but sophisticated solution using GVEtal modded d2nt:

Hope this helps, happy botting. Let me know if I can help in any other way.
