any use for ttar?

He is still useful in gengar and jynx solo and on my latios B team.

I get a Mewtwo invite every week, pretty useful for that matchup. Dragon claw Latios faints 6 maxed dragons (all varieties) pretty quick

It sounds like you just don't like TTar and that's fair. I only use him for Alakazam raids so he hasnt seen much use lately but I will use him for Latios

Ttar just won my last 2 Jynx solos and survived as a 6th filler against Gengar. I use it against Mewtwo as well when we’re short manned.

And I’m looking at you, Alakazam, in case you dare a comeback: this time I’ll kick your ass for good.

I use Tyranitars as either the anchors of my team 1 in larger groups or as team 2 when going with less people. Rayquaza and Dragonite have a noticeably smaller TDO and I'd rather not dip too deeply into my current reserve of 100 Max Revives. Most of the time the DPS difference between Dragonite and TTar won't translate to another damage ball anyway, so why waste healing items. If one were swimming in healing I guess it wouldn't matter, but fighting gyms and doing solo challenges keeps my stock reasonably low.

I do agree that Tyranitar is overvalued in here. I love using my legacy Gengars so I would never use a team filled with Tyranitars anyway.

But he's key in Alakazam solos and Mewtwo trios.

I find plenty of uses for ttar:

-One of the best counters for Jinx and Gengar raids - does plenty of damage while also having considerably more survivability than other counters. Especially useful against weather boosted ones.

-Latias - Dragonite takes way too much damage. If that's never a problem for you, fine, but that's already a good niche use for ttar, which only goes to show it is not outclassed. Also, while dragonite does a bit more damage, you also get delayed by being autoswitched when your dragonites faint, so the benefit in using one is marginal. Not to mention it's much easier to dodge with ttar if you want to do so.

-Mewtwo - best counter, hands down.

-Gym sweeping - machamp works best usually, but not always. It depends on what kind of pokemon are in the gym. Ttar has a 3 bar charged move, which makes it easy to control your damage output while sweeping, as well as Bite as its quick move, which is easy to dodge with. For me, ttar is the second best generalist after machamp.

EDIT: With respect to generalists, I should note that I don't have a powered mewtwo yet.

Just because he gets outclassed by dragons this raid boss doesn't mean hes far behind. Hell with lugia he was the top used mon because not everyone has 6 powered up zapados, raikou, or legacy shadow claw gengars.
Plus there are a lot of pychic Pokemon yet to be released that will be tier 5 such as Deoxys, azelf, and cresselia. Ttar will be the goto mon for these raid but be slightly behind legacy gengar as hes a glass canon.

A small note on your tier 3 solo attempts using Ttar, pinsir is a terrible idea because all of pinsir's moves except vice grip are effective on Ttar, and with rock smash/close combat dealing 4X to ttar

Ttar can be very good on the double psychic versions of the current legendaries. By far the most tanky, but tbh Dragons will handle the double psychic versions better as well as they do not hurt as much as the dragon sets.

If anything, hear this: Any power up of a pseudo legendary (all 4 in the game right now) or meta-relevant legendary, provided IVs are good, is never going to waste.

Why don’t you go ahead and transfer them all since they are useless. Nothing anybody has said here will change your mind and they take up soooo much storage space. Well we are waiting.
