Answer 1

The react-router-dom Link (LinkAnchor) uses an <a> Tag, which has underline per default.

It should work if you add textdecoration: none to the <Link> Tag:

<Link to="/" style="text-decoration: none">
    <Button color="inherit" onClick>Log Out</Button>
</Link>

(Note that Browsers might behave differently, but this solution should work for all, to my knowledge)
