Probably yes, as the manga scan shows Yata mirror expanding to protect Itachi from another side..., but even itf this is true then Yata and Totsuka Blade still have possible weakness for enemy to use as I stated in my thread.
Possible ways to bypass Yata Mirror:
1) Attack from the back or the side
2) Attack it with two different attacks at the same time... or use KKG, KKT or simplu Ying-Yang release
3) If Attack contain more chakra then wielder of Yata then wielder's lack of chakra will be left with attack and will hit Wielder
4) The Shield can be taken away...
Possible ways to not be defeated by Totsuka Blade
1) Breaking Genjutsu, Dream Word and release yourself
2) If Blade can't pierce you then you can avoid being sealed
3) Stopping/ breaking sealing technique with which Blade is enchanted with so anty sealing techinique
4) The Blade can be taken away
So if you try imply that Itachi can be invincible to call him Solo King then sorry but he is not. At least not yet until Kishi states otherwise proving me being wrong.
Here is my thread elaborating on Yata Mirror and Totsuka Blade possible weakness, enjoy:
