Below is a minimal example which doesn't rely on the module,
the problem is caused by the order of the \noindent and \parshape
command.

When a paragraph starts before the \parshape values are set
the arguments are ignored because the values are already frozen
at this moment, when you set the values before the paragraphs
starts ConTeXt applies them.

\starttext

\hsize 10cm

% lettrine module, \noindent before \parshape

\noindent
\parshape 3 1cm 9cm 1.5cm 8.5cm 0cm 10cm
\input weisman

\blank

% working order, \parshape before \noindent

\parshape 3 1cm 9cm 1.5cm 8.5cm 0cm 10cm
\noindent
\input weisman

\stoptext
