If you have access to JMP Pro you could do this with Formula Depot.

You can select the formula columns, select copy columns, open new script (ctrl + t) and paste there. Then search in script editor.
You could also try removing that column and if it is being used, JMP will display warning like

Edit:
There might be also some way in JMP18 utilizing Columns Manager but I could figure one out. Data Dictionary almost can do it but it stores the formulas as images so they cannot be searched easily

And of course there is plenty of pure scripting options
