The short answer to your question is no. The long answer is that they have some dishes that are like that, and they built their name on some of those dishes + hype of being “crazy temple of meat” somehow. All of that hype died at least 5 years ago, though.
It’s also entirely a la carte, so how you eat there is up to you. But looking at their current menu, the crazy heavy dishes are pretty much all those “classics” like the two foie gras dishes (biscuit + gravy and the loco moco) and the classic oxtail “poutine” as well as the rabbit;s legs, which by now as basically in that classic category. I think the bone marrow with chimichurri and caramelized onions also a heavy classic. Some might through their classic BBQ pork belly sandwiches in that category or the melted p’tit basque, both of which are also dishes that have been on the menu forever. (Balsamic pork ribs and the smoked turkey leg are also classics, but neither feel very heavy to me; they turkey leg is quite possibly the best turkey leg I’ve ever had).
Nearly everything else on their menu looks rather light and finessed.

Unless dishes like:
boniato yam, lemon crème fraîche, pepita, salsa verde, za’atar
market citrus, kohlrabi, pecan, ricotta salata, chili oil
tandoori octopus, tamarind, yogurt, kumquat
peads and barnetts pork toro, plum char siu, cabbage, kanzuri, green garlic
Sound like monstrously heavy?
Admittedly, they serve a few newer dishes like:
pork katsu, yuzu aioli, mustard greens
quail fry, grits, slab bacon, kale, maple jus
bone-in ribeye, potato aligot, foie gras sauce
Perhaps the use of aioli with katsu is a bit too over-the-top for most people, or the inclusion of bacon AND fried bird in grits is enough to make someone faint at the mere thought. Certain intellectuals might wonder whether it’s really necessary to serve a ribeye with potatoes aligot and foie gras sauce, and it is true that the dish seems crafted to put diners into early graves, but supposing you are aiming to live a bit longer, these dishes are pretty easily steered around when dining it seems.
Personally, I enjoy both aspects of Animal; and I will say this about the heavy dishes, typically they are not heavy for their own sake, but pulled off with a lot more finesse than one would imagine from the descriptions and photos.
The real sad thing about Animal is that they don’t have cocktails… =P
