BLOBs in sqlite can be up to 2GB or less, depending on the compilation flags. If you store 2GB and the other application uses sqlite compiled with support for less than 2GB BLOB size, good luck on getting them to work... If you want to store content larger than 2GB in sqlite, you have to chunk them, manage the chunk sequences, etc. And you can't overwrite a fixed size 2KB portion at the specified offset, you'll have to rewrite the entire 2GB chunk.
