There is no direct function to rotate legends in graphs using MATLAB.
However, as a workaround we can manually rotate the legends. Please refer to the following example:
% create a sample plot
h1 = plot(1:5);
% add legend to the graph
[legend_handle, icons] = legend('Sample legend');
% disable the box around the legend object
set(legend_handle, 'Box', 'off')
% get the current position of the legend object
% assign the required position of the legend to a new variable
new_leg_pos=[.7 0.6 .2 leg_pos(4)+.2] ;
% Get current line data (horizontal line)
xd = icons(2).XData;
yd = icons(2).YData;
% Swap X and Y data for line (make vertical line)
icons(2).XData = yd;
icons(2).YData = xd;
% Rotate and reposition the text
icons(1).Position = [0.5 0.4 0];
% Adjust legend size to accomodate changes.

I do have the same problem and I'm working with R2020a.

This only works on the plot figure, when i use the 'errorbar' function same error shows up.
