No it hasn’t, it never will, und you reveal yourself as an illiterate if you write that way. The exception may be „Eigennamen“, but only because strictly speaking there are no orthographic rules for them. Lebensversicherungsgesellschaft isn’t one.

You wouldn’t include the s when you dash the words. Hausratsversicherung but Hausrat-Versicherung.

The university’s name is even more egregious. It’s not the university of Eberhard Karl (that’s two different persons), but the s implies ownership of said person. It only appears in records after 2012 as far as I know.
