I don't see the rip off. I think it's about 60% similar but your design isn't special at all and very generic. The idea that someone "ripped you off" is a huge stretch to me.
Otherwise, yes I agree, it's not a particularly innovative design, and 'graph with breadcrumbs and a datatable', and 'SQL query builder with madlibs type interface' are pretty generic, the implementations here are nice, but look very similar to Airtable/Notion/Coda, I don't think there's a huge amount of originality there. On the line between 'inspired by' and 'copied from', I think.
