I should better explain my use case:

I would like to create my own seed by using dice throws. When I have a 99 digit base 6 number, I want to type that into Bitcoin Core on an offline machine/live os. Then I want to take the XPUB that is created, and transfer it to an online machine running Bitcoin Core as "watch only". Then I can create new receiving addresses on the online machine, which I will also use to create PSBTs.

I don't mind using a simple script or two if absolutely necessary, but I prefer to only use Bitcoin Core for security reasons.

It seems this is simply not going to be possible. From Bitcoin Core v23:

the legacy wallet type is being deprecated and support for creating and opening legacy wallets will be removed in the future

I will not be able to update my version of Bitcoin Core beyond v23. I will have to use "legacy" wallet types only for my use-case.

- createwallet "wallet_name" ( disable_private_keys blank "passphrase" avoid_reuse descriptors load_on_startup external_signer )

descriptors will have to be set to false.

Then I can use:
- sethdseed ( newkeypool "seed" )

I will set newkeypool to true, and the "seed" is the WIF private address that is generated by the python script provided by BlackHatCoiner.

After that I can use:

- getnewaddress on offline machine, then save this to text file and import into bitcoin core on online machine using
importaddress "address" ( "label" rescan p2sh )

And then, when I am ready to spend:

- estimatesmartfee/createpsbt on server (to build a transaction with current fees)
- save the transaction in a text file, take to offline machine
- walletprocesspsbt on offline machine, save to text file and take to online machine
- broadcast transaction

Is this generally correct?

This way I have a paper copy of my original seed (a random 99 digit number in base 6), I have an offline machine and electronic copies of an encrypted wallet.dat file with private keys, and I have an online machine which never sees private keys but allows access to the bitcoin network.
