Video is composed of multiple, quick exposures in succession. While a long exposure shot may take as long as video — although what we might consider a short video makes for a quite long single still exposure! — it's just one exposure: the shutter opens, stays that way, and closes when the shot is done.
If you take a 30 minute long exposure, that's one frame at a rate of.... ¹⁄₁₈₀₀th of a frame per second. (Of course, we don't normally say that, because it's kind of silly and not useful at all.)
It is possible to create an effect similar to a long exposure by blending multiple frames, and some cameras can even do that as a special feature. But this is a special case and probably not what you are concerned with.
Still camera specifications do often list FPS, though, separate from video mode. This is for something entirely different from FPS in video — it's for taking a series of separate still photos in a rapid sequence. This is useful when there's a crucial moment that it's tricky or impossible to time, like getting the exact moment of a catch or hit in sports. But here, these are very short exposures, with no relation to long exposure.
