The only animal/caffeine studies I’ve found were either about it being pretty deadly to insects and mollusks, or just it being a toxin to animals in general. That didn’t rule it out to me, since pretty much anything that gives you a buzz is because it is disrupting your vital functions in some way.
There is probably much more coffee on farms these days as opposed to wild coffee, so if coffee farmers aren’t reporting the coffee being eaten directly, or noticeably high predation of what does eat the coffee, I’m going to say it sounds like it’s not a thing. It would probably be hard to select which animals actually ate enough coffee to get an indirect caffeine jolt from, and it could work the other way as well, if they consumed something that ate more beans than the predator could handle, making them sick.
With the dolphins chomping on the blowfish, it’s not like the fish is sometimes poison and sometimes not, so it’s simpler to figure out what to do.
There was a test on zebrafish and rodents testing their reactions to unwanted stimuli, and it seemed to boost their reactions, but not in all cases, so effects seem to vary by species and individual. So maybe it is just a happy surprise if they eat something weird.
This is still really cool to think about, because I never really thought of an animal actively seeking out another as prey not only as food but also for other properties like chemicals that that animal may have ingested. In this situation is seems like an edge case if it ever did happen, or just as you said a happy surprise. Though that does make me wonder if there are any other instances of this in other animals and also how often it might be un-recognized by researchers. Lots of food for thought there.
I’ve been unable to find any helpful info.

The closest things I can think of off the top of my head would be:
Ants farming aphids
Deer eating bones
Carnivorous plants sort of came about the same way if I’m remembering correctly as well.
We put out mineral blocks for the wildlife, and they’ll keep coming long after the block is physically gone and lick at the ground.
