If the .csv file looks similar to Daysim's .ill file Honeybee can calculates the values for you without re-running the analysis.

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 cases you will need to build a new model in the host program(s) before running the analysis and getting your desired results.
