Which is not worship. Any more than David was worshipping the angels when he addressed them in Psalm 103:20.
"False attributes have been attributed to her regarding her perpetual virginity, conception, her intercession, etc."
A statement which begs the retort "says you."
"Icons/relics are maintained in houses"
And...? So what?
Let's put this verse in it's proper context shall we and not attempt to use one verse out of context to support a non-biblical position.
For those playing at home here is Psalm 103. I have bolded the text where David says to offer praise to God, which is quite different than praying to God.
Praise the Lord, my soul; all my inmost being, praise his holy name. 2Praise the Lord, my soul, and forget not all his benefits— 3who forgives all your sins and heals all your diseases, 4who redeems your life from the pit and crowns you with love and compassion, 5who satisfies your desires with good things so that your youth is renewed like the eagle’s. 6The Lord works righteousness and justice for all the oppressed. 7He made known his ways to Moses, his deeds to the people of Israel: 8The Lord is compassionate and gracious, slow to anger, abounding in love. 9He will not always accuse, nor will he harbor his anger forever; 10he does not treat us as our sins deserve or repay us according to our iniquities. 11For as high as the heavens are above the earth, so great is his love for those who fear him; 12as far as the east is from the west, so far has he removed our transgressions from us. 13As a father has compassion on his children, so the Lord has compassion on those who fear him; 14for he knows how we are formed, he remembers that we are dust. 15The life of mortals is like grass, they flourish like a flower of the field; 16the wind blows over it and it is gone, and its place remembers it no more. 17But from everlasting to everlasting the Lord’s love is with those who fear him, and his righteousness with their children’s children— 18with those who keep his covenant and remember to obey his precepts. 19The Lord has established his throne in heaven, and his kingdom rules over all. 20Praise the Lord, you his angels, you mighty ones who do his bidding, who obey his word. 21Praise the Lord, all his heavenly hosts, you his servants who do his will. 22Praise the Lord, all his works everywhere in his dominion.
I believe we can conclude from this perspective that David is saying we and everything should be offering praise to God and God alone.
"False attributes have been attributed to her regarding her perpetual virginity, conception, her intercession, etc." A statement which begs the retort "says you."
Not one of which can be supported Biblically unless you do some really crazy twisting of a very few verses and take them out of context.
"Icons/relics are maintained in houses" And...? So what?
The Bible makes it clear we are not to have false idols or worship false idols.
