that theme uses font instead of fontsize. so, it's legend is defined as:

 legend: {
              itemstyle: {
                 font: '9pt trebuchet ms, verdana, sans-serif',
                 color: '#a0a0a0'
              },
              itemhoverstyle: {
                 color: '#fff'
              },
              itemhiddenstyle: {
                 color: '#444'
              }

        },

if you define your's with both font and fontsize, it'll work (seems like a bug to me, but maybe it's a feature):

 legend: {
              itemstyle: {
                 fontsize:'20px',
                 font: '20pt trebuchet ms, verdana, sans-serif',
                 color: '#a0a0a0'
              },
              itemhoverstyle: {
                 color: '#fff'
              },
              itemhiddenstyle: {
                 color: '#444'
              }

        },

i assume the title has the same thing going on.
