Pandapodium has added a bunch of bags from voicevelo: https://www.pandapodium.cc/product-category/accessories/bags/
Not cheap but they look great and are available in more colors

Not Ali, but found these on Amazon. Cheapest bolt on top tube bag I've seen.

I used to purchase these Blackburn top tube bags from Walmart several years ago, when they cost $8.95 in 2022.  I like them because this is where I keep my cell phone for quick access.    (I see that the price has doubled in 2 years.)
