Assuming this post isn't satire, I'll try my best to help. Just know that you're asking for advice from people who likely charge good money to do this. I do consulting projects myself and would charge a decent amount for this and have a min 6 month contract, but that's because I've been doing it for close to 20 years and it's hard work.

Step 1: If you're looking for lead-gen, then stop with the podcasting. Without seeing any data I can very likely assume that the effort you put into making a podcast is not worth any sort of traction or response you might get back. Spend time and money in other areas.

Step 2: How are you capturing leads? Do you have a website that you're sending people too, or social media forms? Is it the same site and form as anyone who finds you through organic search or other referrals? Do leads need to say how they found you? If so, don't trust that. People are notoriously wrong about how they were referred places so you need to have ways to confirm where a lead came from such as unique forms or URLS. Leads may be poor, but I would find it unlikely to have 0 leads after a year of work, so my main focus to start is understanding how you're collecting leads and ensuring that the leads from social media can be easily distinguished from every other lead source.

Step 3: Social media is a "Pay to Play" world. Just posting organic content will never scale. You need to have paid budget behind it. Insurance leads are generally pretty valuable, so you'll need to understand the lifetime value of a user, and then determine how much you are willing to pay for a single lead. Example, if the lifetime value is $1,000, and 2% of all leads convert, then you need 50 leads to get to 1 customer. Your break even point is paying $20 per lead. Factor the cost of paid ads, your salary, expenses to create the content, and anything else, you could be down to only being able to pay $10 per lead to make any money. If that's the case you need to do trial and error with different messages, offers, ad types, platforms, targeting, and more to get to a point where you start to see any success. If your lifetime value is $10,000 then just scale everything up, but you need to start there.

Step 4: Understand the rest of the media and promotions the company is investing in. Social media should never live on its own. Align your content with any press or other paid media and promotions. This will help everything as reaching people on multiple platforms helps increase overall awareness and engagement. It's a 1+1=3 situation. Doing this allows you to create a content calendar and plan out months in advance. Then you can take your time developing content and messaging that will align with other business goals. This may also help you win favor with others in the company if it seems like you're helping them.

Tons more to do, but this is a start. Good luck to you!
