There's a macro in the thread @tiffle linked to that shows how to automate the open/save dialogue with JPEGmini here: Wanted: Keyboard Maestro Automation with JPEGMini
But honestly, unless there's some reason you absolutely have to use JPEGmini, I would follow the advice in the post directly after that one and try ImageOptim instead if you want anything that's truly automatable: https://imageoptim.com/mac
