When using the Massive Dev Chart for film development, is the listed development time the total time including agitation, or should agitation be added on top of that time?

Agitation time is included in the development time.
Assuming you are using a small tank (this type seems to be the most common) the agitation is by inversion.
You start your timer, pour the developer in, seal the lid tightly, tap it to your table forcefully (to let the bubbles go) and then proceed to invert the tank for the first 30 seconds. Then invert 3 or 4 times on each minute.
If you like the Massive Dev Chart you will love the Massive Dev Chart Timer app. It has all the times + audible timer. I found that very helpful.
As always: if in doubt consult the film datasheet - https://www.ilfordphoto.com/amfile/file/download/file/1903/product/694/ - it will give you a good baseline for your process to build upon.

Yes. The development time listed on the Massive Dev Chart is the total development time, and it includes the agitation periods.
A typical small-tank process is: start the timer as you pour in the developer, seal the tank, tap it to dislodge bubbles, then agitate continuously for the first 30 seconds. After that, agitate for a few inversions at each minute, following your chosen method or the film/developer instructions.
If you want the most reliable baseline, check the film or developer datasheet, since manufacturer instructions should take priority over any chart.
