Ordinals got easier with 1.3.0 https://github.com/paulmillr/scure-btc-signer/releases/tag/1.3.0

This works for me:

const tx = new btc.Transaction({ allowUnknownOutputs: true });
const opReturnData = new TextEncoder().encode("hello world");
const opReturnScript = btc.Script.encode(['RETURN', opReturnData]);
tx.addOutput({
    script: opReturnScript,
    amount: 0n
});
