The space issue affected only the chainstate, not the blocks (it runs in pruned mode).
But I do wonder if there may be some inconsistency in the chainstate or block data, despite the fact that it doesn't complain and everything seems to work fine.
By the way, I've had it crash twice due to disk space. The second time the GUI's error message complained about something else, maybe a block hash mismatch, but the log only mentioned LevelDB running out of space.
The last time I checked, Bitcoin Core shuts down gracefully upon running out of disk space so not really a lot of concern for any corruption there. Even if there is, it wouldn't be a big issue, just replace your data.
The leveldb should have CRC32 checksum for the records and would throw an error upon a mismatch.
