To what extent do those who hold to a 'literal' account of Genesis 1-11, such as YECs, hold there are symbolic elements in Genesis 1-3?

YECs (Young Earth Creationists) often hold their views because of a 'literal' view of Genesis, and in particular the use of 'day' in the Genesis creation account. Are there aspects of Genesis that 'literalists' generally hold are symbolic, figurative, or not holding their 'usual' meaning, however? For example, do they hold there was literally a sword used to block the entrance to the east side of the Garden of Eden (Gen. 3:24)? Similarly, do they hold the Tree of Life is literally a tree that literally can be eaten to bestow eternal life? Similarly, do they hold a serpent literally spoke to Eve? Similarly, did God literally breath into Adam's nostrils? Similarly, was there literally an evening and morning before there was a Sun? And so on. How do those who take a 'literalist' approach to Genesis, such as YECs, generally understand these sorts of elements of Genesis? Are there any elements of Genesis 1-3 that *are* generally taken to be symbolic by literalists?
