The fact that the phono stage does not invert is meaningless. The signal still passes through the line stage after leaving the phono stage, so even when using phono your output will be inverted when leaving the AI, period. You have what is called an integrated preamp, which is similar to an integrated amp. Instead of a preamp and amp in one box, you have a phono stage and line stage in one box. As you become more familiar with seperates, you will realize that the phono stage runs through the line stage and then on to the amp.
Bottom line, everything coming out of your AI will be inverted. The only concern you would have is if the phono stage also inverted, which would then cancel out the line stage's inversion. However, it does not, so you have no worries.
So change the polarity of your speaker cables only once, either at the amp output OR at the speaker input. Note that if you change polarity at both ends you will defeat the purpose.
Hopefully this helps.
