I never did dig into this as it still was a bit above my head, but it
seems like this could do what you want:
- https://lists.gnu.org/archive/html/emacs-orgmode/2013-03/msg01329.html

In other words, you'd define a custom function like this:

(defun mapcdi-org-latex-headline-function (todo todo-type priority text tags)
  "The docstring of my function."
  (concat
   (and todo (format "{\\bfseries\\sffamily %s} " todo))
   (and priority (format "\\framebox{\\#%c} " priority))
   text
   (and tags
        (format "\\hfill{}\\textsc{%s}" (mapconcat 'identity tags ":")))))


I think you'd just omit that "text" bit, and probably remove the other stuff to.

ETA: I just went ahead and gave it a whirl. It looks like this, or
something close, should let you do whatever you want with headlines
(go ahead and use priorities, tags, todo keywords, and the like and
still just get a blank headline:

(defun mapcdi-org-latex-headline-function (todo todo-type priority text tags)
  "The docstring of my function."
  (concat
   (and todo (format "{}" todo))
   (and priority (format "{} " ))

   (and tags
        (format "\\hfill{}\\textit{}" (mapconcat 'identity tags ":")))))

There most likely is a blank line where the headline *would* go. I
played around with trying to \vspace a negative line space like so,
and I think it's doing the right thing, or is at least close (there's
less space between the contents line and the paragraph text):

(defun mapcdi-org-latex-headline-function (todo todo-type priority text tags)
  "The docstring of my function."
  (concat
   (and todo (format "{}" todo))
   (and priority (format "{} " ))
   (and text (format "{\\vspace{-\\baselineskip}}" ))
   (and tags
        (format "\\hfill{}\\textit{}" (mapconcat 'identity tags ":")))))

The only thing I noticed is that within a section, paragraphs by
default have no space and are indented (well, the first isn't, but
following paragraphs are). With this method, paragraphs within
sections are going to have the typical post-section spacing compared
to being treated like truly consecutive paragraphs. If you're okay
with that, then this will work. If not, you'll have to make a custom
latex template somehow so that the whole document is treated like one
long section. I'm not sure if that's possible given org's headline ->
section internals. You might be able to fiddle with something like the
above \vspace{} trick, though? You'd also have to have every paragraph
indented so that they weren't treated like the first paragraph in a
section (un-indented).

Anyway, hopefully this gets you on the right path!

#+begin_src test-file

#+bind: org-latex-format-headline-function mapcdi-org-latex-headline-function
#+options: num:nil

* todo headline 1       :test:

blah blah blah.

* headline 2

blah blah blah

* headline 3

A couple of separate paragraphs to see how far apart two paragraphs would be
normally. We'll add enough to line break just to make it interesting.
