In general, I know of no available tools that would take either of these input formats and compute DA, unfortunately. Again, you can use a spreadsheet to take the illuminance values (option two in your post) and plot them, or you could use OpenStudio to take an idf (option one above -- assuming it has all the daylighting objects properly placed) and run it through an annual simulation with Radiance, which will produce a summary csv file which does a lot of the work for you.
Many of the other tools out there (e.g., Honeybee, DIVA for Rhino, SPOT) that are geared toward climate-based daylight modeling have their own methods for reporting DA and other dynamic daylight metrics, as well. In most of these sases you will need to build a new model in the host program(s) before running the analysis and getting your desired results.
