I thought it could be done through a combination of settings: an infile
setting of H:3 (or thereabouts) and a BIND setting of org-export-latex-low-levels to
nil.

C-h v org-export-latex-low-levels RET says:

,----
| org-export-latex-low-levels is a variable defined in `org-latex.el'.
| Its value is itemize
| 
| Documentation:
| How to convert sections below the current level of sectioning.
| This is specified by the `org-export-headline-levels' option or the
| value of "H:" in Org's #+OPTION line.
| 
| This can be either nil (skip the sections), `description', `itemize',  <<<<< the doc says it can be nil to skip them
| or `enumerate' (convert the sections as the corresponding list type), or
| a string to be used instead of \section{%s}.  In this latter case,
| the %s stands here for the inserted headline and is mandatory.
| 
| It may also be a list of three string to define a user-defined environment
| that should be used.  The first string should be the like
| "\begin{itemize}", the second should be like "\item %s %s" with up
| to two occurrences of %s for the title and a label, respectively.  The third
| string should be like "\end{itemize".
| 
| You can customize this variable.

Unfortunately, there is a bug in org-latex.el, in org-export-latex-subcontent
