The only public bots available at the moment for Sword/Shield are only for den-based interactions. There are bots that, for example, let you build a mon the way you want it tand then the system will trade it to you.
But all that stuff is worthy for vanilla consoles. If yours is hacked, simply download PKHeX (that has been around for a loooong time), back-up your save files with Checkpoint or a similar homebrew, move the files to your computer and modify them as you want.
