<h3 id="summary-problem-motivation">Problem/Motivation</h3>
<p>In order to make the <code>OpenAiBasedProviderClientBase</code> class more open, we should refactor the <code>loadClient()</code> method to create the client from a separate method.</p>
<p>It will allow providers like Ollama to create the client without authentication.</p>
