The point of a land value tax is not to make housing more affordable, but to ensure land goes towards the most productive use. If LVT was implemented along with zoning reform, housing would indeed become far more affordable because lots of more housing would be built. But a government subsidy for lower income families to pay below market land rent is a very different policy and has none of the benefits of LVT.
