I'm not familar with Miller columns, but if you're changing the behaviour of your file browser, then I'm not sure why you're suprised single click might not work as intended.

Miller columns have been one of the default views in OSX Finder for about two decades, opening and selecting at the same time is how they are supposed to work. Here's a demo video: https://www.youtube.com/watch?v=yQ7trdpY9MI
I think miller columns was part of KDE file manager for some time, before they decided they were too complicated for developers.
Ok, I see what you mean by Miller columns now. I guess I wouldn't consider that image preview on ths side 'opened' though. 'Opened' to me would mean launching a dedicated image viewer with that file.
When using miller columns in Finder, you will open a folder at the same time as you're selecting it. Files will only preview.
