Now I (only) need the UTXO database and check each generated address against it.
Should I extract addresses with balance from the blockchain and put them in a sql database or something?
What would be the general approach for such a thing?

Yes. You should parse blockchain and get the set of utxo.
The set is not very large.
https://statoshi.info/dashboard/db/unspent-transaction-output-set
There are ~32 mln unspent outputs today according to statoshi.info
It is quite possible to hold this set in memory in hashtable.
You can even use plain-text file for storing this data without using SQL engines.

I think this is enough information for me to proceed further. Thanks for pointing me in this direction

I'm busy doing number 2.

Let us discuss number (1). I can create such engine for you. Not for free of course.

Well, I like your offer, but I only lost some satoshis. The amount of electricity I used to type this message is probably already worth more.
I like to get them back and learn from everything in the journey to reach that goal. I already learnt some python and want to see how far I can get on my own.
If in the end I'm not smart enough to build everything myself I probably won't hire someone else to do it for me. Unless those satoshis become valuable enough to do so.
