I don't think this program should have any config file at all.

Unless the command line tool is very complex (which this one is not), then the user should always have a fresh start each time the command line tool is run.

I'll elaborate further in an other comment.

While there is a option to skip looking for the blender binary, this is very bad design for a command line tool.

Why? Because this makes it very tedious to script this or run it on multiple computers.
And most importantly, it will stop execution and ask for user input.
For batch scripts this makes it very unreliable because not only does it not do what you wanted to (crawl for blender files), it also stops execution until it has gotten input.

This means that if someone has set this up to run in a bigger script, the script will halt and never finish or give any errors indicating that it didn't execute.
