If the president air strikes people and uses drone strikes using whatever system congress has said that makes that "okay" then he cannot be prosecuted for murder while authorizing and ultimately conducting drone strikes (in most circumstances).
However, if the president is having is own feud with some guy he doesn't like and finds a way to get him drone struck, that would not be covered by immunity because he wasn't acting as president in that capacity in any legally recognized way.
Why not? US presidents have murdered US citizens abroad with drones. All he needs to do is claim he did it under national security. SCOTUS explicitly calls out that the presidents motives are immaterial for determining immunity or not.

I thought the USA was a country of laws, not kings.
* actually guaranteeing that if the president is trampling my rights and a supermajority of congress don't like it, he'll be ejected from office, not anything to do with my protection or restitution.

Intimidating the court into ruling in your favor with guns to their heads is an official act until the court says it isn't official, but the court can't say it isn't offical, because they've got guns to their heads.
That this system fails to work when it's axioms are ignored (i.e. in the stated case of a coup) cannot be construed as a failure of common law or an indictment on its 950+ years of success. Such act would be a failure of the Executive solely.
The founder's stated intent for resolving such a situation is why we have the 2nd amendment.
Many disputes about presidential actions are about what the constitution allows.
The majority said In dividing official from unofficial conduct, courts may not inquire into the President’s motives. Nor may courts deem an action unofficial merely because it allegedly violates a generally applicable law.[1]

Since imprisoning the president would obviously intrude on the functions of the Executive branch, it really looks like the majority opinion is that no president may be prosecuted for any "official act".
> In dividing official from unofficial conduct, courts may not inquire into the President’s motives. Such a “highly intrusive” inquiry would risk exposing even the most obvious instances of official conduct to judicial examination on the mere allegation of improper purpose. Fitzgerald, 457 U. S., at 756. Nor may courts deem an action unofficial merely because it allegedly violates a generally applicable law. Otherwise, Presidents would be subject to trial on “every allegation that an action was unlawful,” depriving immunity of its intended effect.
> unless the Government can show that applying a criminal prohibition to that act would pose no “dangers of intrusion on the authority and functions of the Executive Branch.” Fitzgerald, 457 U. S., at 754. Pp. 12–15.
This seems to be the real boundary. To show something doesn't have immunity you either have to:
1. Show it was an unofficial act
2. Show it wasn't part of the core presidential powers and that prosecuting it wouldn't have any danger of intruding intruding on "the authority and functions of the Executive Branch."
I think that last standard is related to presidential immunity from subpoena which courts have also recently construed quite broadly
When it comes to it, this exact thing will be covered by immunity because of how things work.
