My intention is simply to have an operation that I can run on target
strings (probably mostly code, maybe even a regex string that I want to
interpret literally) so that I can use the result as a regex search
string, meaning what it's supposed to.
I'm not sure that I actually need anything more than what I've already
suggested, but maybe I'm missing something.

I suspect you’re opening a can of worms. Can you not just turn of Grep search?
See

Escaping everything might be safe but hard to read —
https://en.wikipedia.org/wiki/Perl_Compatible_Regular_Expressions:
Like Perl, PCRE has consistent escaping rules: any non-alpha-numeric character
may be escaped to mean its literal value by prefixing a backslash
