Uninstalling apps, appcleaner, still have questions!

I am looking to remove Logi Options+, and on the one hand I get it's (usually) no big deal to just have some random orphan files hang around, but still want to understand. The Applications folder only has the one Logi Options+ app, but appcleaner sees both a logi options+ as well as the pluginservice - where is this "app"? If I just Trashed the main app, would this just linger around? Clicking on the logipluginservice lists one file, the LogPluginService.app at 555mb... going to reveal it in finder also shows "Logi Options+ Driver Installer.bundle", but this file is NOT listed anywhere in the main Logi Options+ file list... So, what gives? Is that last file truly an orphan? Would it disappear somehow? Beyond confused trying to understand how your normal process is supposed to just be "Move App to Trash", yet that seemingly would leave TONS of other files around?
