Inserting non-indented text in enumerate/outline

Question

I'm trying to insert non-indented chunks of text/image/graphs into an outline. I would like to avoid nested enumerate environments. Anyone have a simple solution using something similar to what I have below? Thanks!

\documentclass{article}
\usepackage{outlines}
\usepackage{enumitem}
\setenumerate[1]{label=\Roman*.}
\setenumerate[2]{label=\Alph*.}
\setenumerate[3]{label=\roman*.}
\setenumerate[4]{label=\alph*.}

\begin{document}
\begin{outline}[enumerate]
    \1 Some text
        \2 Other Text 
            \3 Other other text
WANTED: to be able to insert text and graph here that is NOT indented
            \3 More other other text
        \2 More other text
\end{outline}
\end{document}

You can use \hspace*{\dimexpr\linewidth-\textwidth\relax} to move the following text all the way to the left side margin:

\documentclass{article}
\usepackage{xcolor}
\begin{document}

\noindent\raisebox{0pt}[0pt][0pt]{\color{red}\rule[-2in]{0.4pt}{2in}}
\begin{itemize}
\item Random stuff. blah blah blah. More random stuff.
\item Random stuff. blah blah blah. More random stuff.
    \begin{itemize}
    \item Random stuff. blah blah blah. More random stuff.
    \item Random stuff. blah blah blah. More random stuff.
        \begin{itemize}
        \item Random stuff. blah blah blah. More random stuff.
        \item Random stuff. blah blah blah. More random stuff.

        \hspace*{\dimexpr\linewidth-\textwidth\relax}\fbox{\color{blue}Nonindented material}

        \item Random stuff. blah blah blah. More random stuff.
        \end{itemize}
    \item Random stuff. blah blah blah. More random stuff.
    \end{itemize}
\item Random stuff. blah blah blah. More random stuff.
\item Random stuff. blah blah blah. More random stuff.
\end{itemize}

\end{document}

The vertical red line shows you where the left margin is.

If you've got more text to insert, you can put it in a minipage whose width is set to \textwidth.

\documentclass{article}
\usepackage{xcolor}
\usepackage{lipsum}
\pagestyle{empty}
\begin{document}

\noindent\raisebox{0pt}[0pt][0pt]{\color{red}\rule[-2in]{0.4pt}{2in}}
\begin{itemize}
\item Random stuff. blah blah blah. More random stuff.
\item Random stuff. blah blah blah. More random stuff.
    \begin{itemize}
    \item Random stuff. blah blah blah. More random stuff.
    \item Random stuff. blah blah blah. More random stuff.
        \begin{itemize}
        \item Random stuff. blah blah blah. More random stuff.
        \item Random stuff. blah blah blah. More random stuff.

        \hspace*{\dimexpr\linewidth-\textwidth\relax}%
        \begin{minipage}[t]{\textwidth}%
            \lipsum[1]
        \end{minipage}

        \item Random stuff. blah blah blah. More random stuff.
        \end{itemize}
    \item Random stuff. blah blah blah. More random stuff.
    \end{itemize}
\item Random stuff. blah blah blah. More random stuff.
\item Random stuff. blah blah blah. More random stuff.
\end{itemize}

\end{document}

If you wish to allow for page-breaking across the "WANTED" text, then using a minipage would not help (since it keeps the contained text together in a box. For this you could use mdframed or a primitive \parshape to reflow the text block boundaries temporarily:

\documentclass{article}
\usepackage{enumitem,lipsum}% http://ctan.org/pkg/{enumitem,lipsum}
\setenumerate[1]{label=\Roman*.}
\setenumerate[2]{label=\Alph*.}
\setenumerate[3]{label=\roman*.}
\setenumerate[4]{label=\alph*.}

\begin{document}
\lipsum[1]
\begin{enumerate}
  \item Some text
  \begin{enumerate}
    \item Other Text
    \begin{enumerate}
      \item Other other text \par
      {\parshape 1 -\itemindent \textwidth
      \lipsum[2-5]}
      \item More other other text
      \item More other text
    \end{enumerate}
    \item Some more text
  \end{enumerate}
  \item Some other text
\end{enumerate}
\lipsum[4]
\end{document}

I've grouped the \parshape settings to localize its effect for the scope of the "WANTED" text. Although not included, the showframe package was added to produce the visible text block boundaries.

See Wrap around a logo at bottom right of page for a short discussion on the use of \parshape.
