>>97175501K-ON is lesbian, yes. KyoANi's best show
Flute lesbians is yuri but never goes anywhere
Hibike is yuri-bait, MC ends up with dude
Nichijou's Mio is completely infatuated with a dude and the show does not (to my recollection) contain any yuri.
Dragonmaid is a good show with some solid yuri and het pairings
Tamako Market has very little yuri, only one girl who likes MC in unrequited love fashion. The movie sequel is all about Tamako and her male crush getting together.
Violet Evergarden is loaded with various het pairings and little to no yuri that I remember.
The better studio for yuri (at least 10-15 years ago) was not KyoAni but rather Dogakobo, with New Game, Yuru Yuri, etc or even Kinema Cirtus (Yuyushiki, Saki Achiga-hen)
