Kneeling before a statue of her violates the second commandment.
Exodus 20:4-6 “You shall not make for yourself a carved image, or any likeness of anything that is in heaven above, or that is in the earth beneath, or that is in the water under the earth.
You shall not bow down to them or serve them, for I the Lord your God am a jealous God, visiting the iniquity of the fathers on the children to the third and the fourth generation of those who hate me, but showing steadfast love to thousands of those who love me and keep my commandments.

"And make two cherubim out of hammered gold at the ends of the cover." (Exodus 25:18)
"In the inner sanctuary he made a pair of cherubim. . ." (1 Kings 6:23)
Taken at face value, these would also be violating the second commandment. But clearly, they are not. We need to read the second commandment in context. The phrase trasnlated "you shall not bow down to them" (לֹֽא־ תִשְׁתַּחְוֶ֥֣ה לָהֶ֖ם֮ וְלֹ֣א) means not to worship them, which is how it's translated in some translations. We also need to interpret kneeling before a statue of Mary in context. Catholics are not worshipping Mary in the sense forbidden by Exodus 20. Catholic prayers said in front of statues of Mary are ultimately directed towards God--in fact, the Our Father precedes the Hail Mary in the rosary.
I'll get to your other posts in a bit, gotta run here--and I apologize for the late response, it's been a long week for catching up on posts.
