This is either a parody of conspiracy thinking or the people involved were given a pile of money to come up with something new regardless of how silly. It could well be that at the end there is a big reveal but I bailed out after wasting 70 minutes of my life.
I have seen previous documentaries say it was The Mob, the CIA, Cuban exiles, American Communists in support of Cuba, Castro, the Military Industrial complex, accidental shooting by his own security detail and so on but none of those match the sheer silliness of this one.
There is actually a good documentary to be made about conspiracy theories being valuable to nefarious people in power as the noise created by nonsense such as this is excellent cover for their activities.
Avoid this "documentary" like the plague.
