On the contrary, it'd be hard not to have an extremely low profile with such a common name.
Add in the fact that it's been 40 years, and nobody has cared one single bit for the first 35 of those years.
Add in the fact that she probably didn't get any author credit for the game, so probably didn't even realize people knew her name.
Remember that the internet didn't exist in the eighties. I wrote a few video games in the 80s, and this is probably the first acknowledgement on the internet ever that the Bryan Larsen that wrote games for T&D software is this Bryan Larsen. And I'm much easier to find than most, since I'm the type of guy who uses my real name on forums like this.
I highly doubt anybody is going to care about my games, and I'm sure she never thought anybody would ever care either. She was wrong, but I'm sure I'm not.
I one time found the author of the book that got me interesting in programming as a kid back in the 80s, and after sending her a message on FB she was happy to find someone remembered it, let alone kept the book on their shelf as a memento.
What does it take to be left alone? What does a person have to say/do for it to be taken as anything but an invitation to search for them?
