Problem: I have a repeatable field group that contains several fields. I would like to use a conditional to test if any of the RFG has a value in one specific field. If so, I would like to show some text in a header. If not, I would like to hide the header.

Solution: One way to accomplish this in Toolset alone is with a View of the Repeatable Field Group. Add a post relationship query filter, so that the parent post is set by the current page ( or the current post in the loop if you're displaying the main post in a View ). Then add a Query Filter for the custom field (or fields), and check that the field value is not empty. Set the limit to 1 post, since all you need to know is whether or not one exists. In the wpv-items-found section of the loop, add the heading information you want to display. In the wpv-no-items-found section, delete the text message. This View is now effectively a conditional that tests if any related RFG have content in the custom field(s) in your query filter.

If you need something more flexible, a custom shortcode approach is probably more practical. You can use the toolset_get_related_posts API to get all the RFGs for a specific post, then loop over them and inspect their post meta values. I can help with toolset_get_related_posts if you need more information. Basically an RFG is treated as a child of the main post. The slug of the relationship is identical to the RFG slug.
