I would faster go for a Rav Kook halachic opinion (even though my Rav disagrees with Rav Kook on many things) than I would Rav Elyashiv.
That doesn’t mean I think Rav Elyashiv is anti-Torah.
And BTW, to your definition of who is Torah observant – no one keeps halacha 100%. So therefore, no one is actually Torah observant. I am sure that isn’t what you meant.
