A Formula 1 car avoids this design flaw, I suggest you upgrade!
To the OP... Yes, as an engineer, I am sure that I could calculate slightly more flex on the left side crank arm due to having to transmit torque through the crank axle to the drive side. However, that difference in flex is going to be minuscule, something best measured with tools a machinist would use. If you are riding in regular street shoes, I would expect the flex in the sole of your shoe to be larger than in the crank. I would agree with those above that this is a setup or bike fit issue. Our bodies are often fairly asymmetrical whether it is noticed or not.
