"While being physically harmed due to a large lottery win likely isn't a huge threat, I don't know what a more dangerous threat could be. "
If you don't devote resources to reducing risk your chances of being harmed because you're rich add to the risks you had before you were rich, but mostly it's a small additional risk. What you apparently can't figure out is either what you said or how becoming rich affects the various chances of physical harm.

Oh, look! A new name to add to the very short list. Or not.
"they were only told as much as we wanted them to know. "
And that's exactly why lottery winners who aren't stupid don't experience significant new risk, and certainly . In most places you can manage to remain anonymous, and if you're smart other people will know you as just a neighbor that moved away or that moved into the neighborhood.
"why trust some random woman claiming that she'll "help," you hold on to your dwindling lottery winnings? Why not put the dwindling lottery winnings into a trust that can't be withdrawn from for a set amount of years? "

Once people start to have money problems it's not exactly uncommon to make bad decisions about how to solve those problems. Different outcomes, of course, but why were so many people who weren't having money problems foolish enough to think Bernie Madoff had some magical financial knowledge that others didn't have? Human nature has it's upsides and downsides. In many cases the downsides decide how a life goes.
