Why do you think so ? 
The codetools will find all referenced units that it finds in the unit search path.

You don't need all files. You just need a starting point: the project.

You don't need all files, as far as I can see.

"The references request is sent from the client to the server to resolve project-wide references for the symbol denoted by the given text document
position."

As far as I can tell this means:

You don't need to do anything except add the project file.

The codetools will use that as the starting point and that's it.
