A lot of these seem to be created with a tool called Blockbench.
As Blockbench was web-based and the Create mod uses raw bench json files, I initially thought of having a parser/renderer of these files. However it would add complexity and maintenance difficulties.
Blockbench recommends exporting to gLTF, so I'll do that.
I did a little research and think it might be possible to render the blocks.
The blocks are mostly as JSON files here: https://github.com/Creators-of-Create/Create/tree/2201d87da7744cf9ee3f83e1e4c21643244f342b/src/main/resources/assets/create/models/block
