I think this is not really inline with the philosophy of the main Lemmy devs. For this to happen, I think someone else would have to do the work of creating the random selection service. If it was popular enough, maybe they’d put a link on join-lemmy.org
Easy, just create the equivalent of multireddits.
Can your instance not do that as is? Just spin up a bunch of fake users and make them all vote on something?
Sure, I also have been trying to learn about how Lenmy works. I haven’t yet found a comprehensive overview that details everything though.

If you search for a community first time, 20 posts are fetched initially. Only if a least one user on your instance subscribes to the remote community, will the community send updates to your instance. Updates include:
New posts, comments Votes Post, comment edits and deletions Mod actions
From: https://join-lemmy.org/docs/users/01-getting-started.html
These previous ways will only show communities that are already known to the instance. Especially if you joined a small or inactive Lemmy instance, there will be few communities to discover.
This issue/post on github has some info: https://github.com/LemmyNet/lemmy/issues/3062
I would also checkout some discussions on !fediverse@lemmy.world !selfhosted@lemmy.world https://selfhosted.forum
As far as I understand, your instance is only aware of a community on another instance if at least one user on your instance has subscribed to that community on the other instance. Perhaps that’s what you’re experiencing?
So, don’t learn to code? If you don’t have any reason to and can’t find any motivation, maybe it’s just not for you.
