Does JFK’s assassination butterfly effect coming decades

First off, the hippies still happen. They were basically the 60s version of the beatniks of the 50s and they weren't just a U.S. phenomenon. There's no reason to think JFK living would have any major effect on the hippies as they weren't a response to the Vietnam War, tho of course they were affected by it.

Second, I don't see Kennedy ending all involvement in Vietnam, tho he likely wouldn't have made the major commitment that LBJ did.

Third, without LBJ as president, there is no CRA in 1964, tho maybe in JFK's second term. The Great Society programs such as Medicare either don't happen or happen in a reduced form.

Carter: If there was no Watergate, then he'd be butterflied. Ditto for the energy & Iran crises.

I never knew Carter was responsible for the 1973 oil crisis before now. Also, the Iranian Revolution would still have happened, tho the result may have been different. (But maybe not. One only need look to our policy in Afghanistan under Reagan/Bush to realize naivety concerning the Middle East was not exclusive to just Carter.)

I suspect the OP might not have been aware there were multiple oil shocks.
