Note that `org-latex-compiler-file-string' must not be set to nil. It is
not considered a valid value and causes undefined behavior.

Not necessarily. If org-latex-compiler is not a member of
org-latex-compilers, we need some sane fallback. Moreover, apart from
org-latex-compiler variable, the compiler can be set locally in buffer
or locally in the subtree. Either way, it is not necessarily clear which
fallback is reasonable. I'd go as far as throwing an error instead of
using "pdflatex", but alas, we already have the existing behavior and
changing it without strong justification can break things for other
users.

Docstring of org-latex-compiler:
