The dock sometimes crashes on my iMac, and I don't want my family to have to go to terminal and type killall Dock, so is there a way I can make a script file that they can double-click on the desktop to run that command?
Why not write an AppleScript with that exact command, and save it on the desktop as a self-contained script? Then they could double-click on it as you said.
Or, they could 'Force Quit' the dock from within Application Monitor.

open up Script Editor, and enter this: tell application "Terminal"
activate
do script with command "killall Dock"
end tell
tell application "Terminal"
activate
do script with command "killall Terminal"
end tell
Save it as whatever you want. I named it "killDock"
This will open Terminal, kill the Dock, and close Terminal.
