Comme point de départ :

Edit : Maintenant avec le texte complet dans le tableau et la disposition des bâtons légèrement améliorée :

Utilisation tcolorboxet enumitempackages :

\documentclass{article}
\usepackage[margin=20mm]{geometry}
\usepackage{enumitem}
\usepackage{etoolbox}
\AtBeginEnvironment{tcolorbox}{%
\setlist[itemize]{nosep,
                 leftmargin=*,
                 label=\textbullet,
                 before=\begin{minipage}[t]{\linewidth}, % <---
                 after=\end{minipage}\medskip}                   % <---
                            }

\usepackage[most]{tcolorbox}
\tcbuselibrary{raster}

\usepackage{lipsum}

\begin{document}
\begin{tcbitemize}[%
