How to have curly bracket spanning items of Itemize
It's not too hard to adapt the answer you already found :)
\documentclass[12pt]{article}
\begin{document}
$\left\{
\begin{tabular}{p{.8\textwidth}}
\begin{itemize}
\item Second line
\item Third line, which is quite long and seemingly tedious in the extreme
\item Fourth line, which isn't as long as the third
\end{itemize}
\end{tabular}
\right.$
\end{document}
The spacing could use some work but I'm too lazy.
