You could make the following paragraph believe that it follows a heading where there's also no indent by appending \@afterindentfalse\@afterheading after the end of the environment. Package etoolbox provides the handy \AfterEndEnvironment which makes this an easy task. \@afterheading also temporarily sets \clubpenalty to \@M (10000), though. If you don't want this after the patched environment one could insert an adapted version of \@afterheading instead.
\documentclass{article}
% environment hooks and patching:
\usepackage{etoolbox}
\makeatletter
% uncomment the following if you don't want \clubpenalty\@M ...
% \let\nearly@afterheading\@afterheading
% \patchcmd\nearly@afterheading
% {\@M}% original temporary setting for \clubpenalty replaced by ...
% {\@clubpenalty}% ... or whichever value you deem right
% {}{}
% ... and use \nearly@afterheading instead of \@afterheading here:
\newcommand*\NoIndentAfterEnv[1]{%
\AfterEndEnvironment{#1}{\par\@afterindentfalse\@afterheading}}
\makeatother
\NoIndentAfterEnv{itemize}
% treat other environments you want to patch accordingly
% dummy text:
\usepackage{lipsum}
\begin{document}
\lipsum[1]
\begin{itemize}
\item foo
\item bar
\end{itemize}
\lipsum[1-2]
\end{document}
The following code saves the original meaning of \indent and redefines it.
Inside a group it sets \parindent to the original value and calls the saved \indent:
\let\SavedIndent\indent
\protected\def\indent{%
\begingroup
\parindent=\the\parindent
\SavedIndent
\endgroup
}
\setlength{\parindent}{0pt}
Thus, like the original \indent the redefined indent starts a new paragraph if it is called in vertical mode. But it will not set the space in horizontal mode like the original.
