Bladebridge had a support for Talend to Databricks conversion but since its acquired by databricks and rebranded as Lakebridge we dont have that support anymore ( Lakebridge for some reason doesn support Talend ). You might want to contact your Databricks representative (Solution Architect or Account executive ) to see if they can help you get some support . They should have a way of making the convertor work with some customization . 

Untill then you can start with exporting your talend jobs as xml files and then using claude code to convert these xmls to databricks pyspark or SQL notebooks . You will have to keep context engineering in mind if your jobs are huge( summarize your jobs and then target individual blocks for conversion instead of converting it all at once) . If you want to learn how to use databricks hosted endpoints from for claude code you can find the details here .
