Litchi does give you the option to take the pictures; It wants to know the angle of the total shot, the amount of photos in horizontal direction and the amount of photos in vertical direction. As a result you will have the photos; you'll have to do the stitching and uploading yourself.
As far as I know, the DJI Go app offers comparable options, but only a number of presets.
Regarding the stitching; there are some tutorials on youtube on how to do it (look for "stitching interactive panorama" or so), but in any case you will need some software to view the panoramas in an interactive way. Facebook can do it, Google maps can do it (not sure if the preparations for those platforms are the same!). Hangar 360 offers the entire stitching and uploading to their website and making it viewable/shareable as a service; all you do is fly to a point and hit "go".
Edit; oh sorry, just now saw the other reply ...
