A: 1- create a conversation bot to recognize a certain keyword and start a conversation flow, providing a link to a form to fill out;
>>> RTILA can help with scrapping web data and feeding it to a bot but it is not a tool to develop a chat bot. There are a number of good bot building solutions on AppSumo for that and we have planned a video/tutorial on how to use a trained chat bot to pickup un-anwsered questions from Qura/Redit/etc and feed the question to the trained bot and get an anwer relevant to your business and post it on that platform
2 - create this form for the customer to fill out online, the form must have a conditional answer option;
>>> Again, RTILA is not a web page builder, rather a Web form submitted so you could for example get inputs form your users within RTILA and in the back or front end go a fill up and submit that info for them on a given form and apply conditional logic to the inputed data before submitting the form or even deciding which form to use depending on the input
3 - use some data from the form, determined by the admin, and automatically fill in the predetermined fields in a document. After the customer fills in, it must generate a pdf and make it available for download to the customer;
>>> It appears that you first need to have a Form/CMS system first and then RTILA can help you automate some of the functionalities but RTILA is not a page builder. For the PDF part RTILA could connect/use a PDF API to send data along with a PDF template to get that PDF generated but it would be more resilient/flexible to get that done by the CMS and RTILA can feed the data and collect the PDF file URL and send it by email etc.
4 - the form must receive texts and files.
>>> These are classic form inputs and once built by a pager builder RTILA can be used to automate form submissions and also forms results/data manipulation post-submission
After the flow, the conversation bot must send the completion message.
>>> RTILA can go to the backend and for each newly completed message it can initiate an other flow

Is it possible to develop this automation
>>> With RTILA alone no. But once you build your Form/Content Management System (CMS) RTILA can automate actions and complement/bridge where the CMS is falling short but it cannot replace a CMS. You could for instance use a combination of Google Forms and Google Sheet to build your content management side and RTILA works very well with Google Sheet to read/write into specific cells/rows/columns while interacting with other web systems and applying needed conditional logic
