I'm running ScummVM on Linux Mint and bought a classic King's Quest game from GOG. The download is an EXE installer, but I'm not sure how to extract the data files ScummVM needs. I remember having to use several terminal commands for another game on my Mac, so I'm wondering what the simplest Linux method is.

You can also try innoextract, but it only works with installers made using Inno Setup. If it reports that the installer isn’t supported, this particular GOG EXE uses a different format. In that case, run the installer through Wine, Steam, Heroic, or another Windows-compatibility tool, then point ScummVM at the installed game files.
The easiest approach is to install the GOG package with a game manager such as Heroic Games Launcher, Lutris, or Bottles. Once the game is installed, open its installation directory and copy the files listed for the relevant King's Quest version in the ScummVM documentation. Heroic can also be configured to launch compatible GOG games with ScummVM instead of DOSBox.

I tried innoextract, but it returned “Not a supported Inno Setup installer,” so I’ll use Wine or Heroic to install it and then extract the files from the resulting folder.
