I have no particular experience with using such at the subtree level.

The answer of Jambunathan makes much sense, for such cases:

  #+BEGIN_shaded
  This will get a color background.
  #+END_shaded

or

  #+BEGIN_mcchangemargin {-1cm}{0cm}
  This paragraph must be moved regarding the normal margins.
  #+END_mcchangemargin {-1cm}{0cm}

  Note -- The above does not work yet correctly, though, because of the
          parameters to be passed onto the LaTeX environment.

But, the problem asked by Suvayu is different because the "todo" here is a
macro, not an environment. Hence the expected output:

  \todo[inline]{\textbf{\textsf{\textsc{TODO} Provide your last offer.}}\\ }

Except from working in such a fashion:

  #+LaTeX: \todo{
  ... your Org text
  is here
  inside ...
  #+LaTeX: }

I don't see (currently) any other way to achieve what you'd like to get.

Best regards,
  Seb
