There are legitimate reasons to at least attempt a Kickstarter from a business perspective, personally I feel the biggest one would be that 'investors' (using quotes there) that come through Kickstarter will never demand or own a share in the company, whereas if you seek traditional investors that would most definitely be the case, and you would to some degree lose control over your company.
From a personal perspective, I won't be backing this project on Kickstarter: it's silly to pre-order a product you don't even know will make it to production, for the exact reason I mentioned earlier: I'm taking a risk providing a company with money, with no guarantees or equity in return. I am excited to see the final product, though.
As for the integration with Lichess the devil is in the fine print:
>> Play against your favourite chess programs and engines. Regium e-Boards are supported by the most important chess platforms:

It doesn't say you can play human opponents on Lichess, only chess programs and engines. Suggesting they would indeed use a bot account. Now IF the product comes to market and IF it would be possible to make this work so that I can play human opponents OTB via internet, that's where you'll find a customer in me.
