> Not in this context no. It should probably be "is that of". Though the sentence might read more clearly as: "An alternate, and preferred within LLVM, strategy for the second use case is that of generic programming."
"An alternative strategy (preferred within LLVM) for the second use case is generic programming". Commas can be used for a lot of things in English, and sometimes even native speakers have to backtrack to figure out what kind of use it is (in this case, they are delimiting a parenthetical, so just use parentheses).

The different "and"'s here are sort of confusing. Maybe "creating a type hierarchy with virtual dispatch" to avoid one of them?
