OK, I see. LyX inserts this code if you use alternating table row colors and your version of colortbl is older than 2022-06-20. In general this code requires LaTeX at least as of June 2022. I don't think there is a solution for older distributions since PassOptionsToPackage would need to be called before the package is loaded (and here it is loaded by the class).
