nak uses the key "1" by default, which is confusing and once a guy made many posts using that key, he set his profile metadata, picture and all that, made a bunch of normal posts, all with the key "1" and while saying he was trying out nak. I didn't have a way to tell him about what he was doing, but that's part of the magic.

Well, Amber has you covered as your mobile signer, as long as you are on Android. I'm partial to Alby as the browser extension, since I also use it for connecting to my wallet for zapping, but Nos2X is a good option, too.

If that is the case, then generating them offline is superfluous. The browser extension or mobile signer will be online and a possible means of the key leaking. You may as well just use the browser extension or mobile signer itself for generating the keys without worrying about being offline when you do it. Your private key is just as vulnerable being held in an application on a device connected to the internet as it is being generated by an application on a device connected to the internet.

How are you planning to log into Nostr apps?

Ah, so the key here is not generating them using a web client. Not that you aren't generating them using an application of any kind. Both of the tools mentioned here are applications. Applications that don't require internet to work, but applications nonetheless.

You're not likely to find user-friendly means of doing this, since it is only really needed by those with a higher threat-model than the average joe.

You can get something like this kind of offline generation of keys using an old Android phone with no internet connection. Just download Amber, turn on airplane mode, then create a new Nostr account in Amber. Once completed, you will be able to back up the private key as an nsec, an ncryptsec, or even as seed words, all offline.

The problem you will then run into is, there is no way to USE your private key offline. It must be accessible by the application you are using to log into a Nostr client. Everything you do on Nostr requires a signature from that key. Good luck finding a convenient way to sign for every reaction, zap, and comment in an air-gapped way.

Unless you are talking about some app that is built into the OS? There are no operating systems that support generating Nostr keys. We're way too small for that.

How would keys be created without using an application? Rolling them by hand with dice?

Local to what? A desktop? Windows? Linux? Mac? A mobile phone? Android or iOS?

On Android, for instance, you can use Amber to generate your keys locally and also use it for signing into other Nostr apps without giving those apps your private key.

Ditto is trash

Ditto is a pretty cool client found at ditto.pub for a public instance. It is intended for communities to run their own instance, though.

Depends on the client. Primal's list of "Topics" in the explore section is just a list of hashtags by another name, and has them in order of popularity. Ditto also has a short list popular hashtags with a small graph of their use over time.
