While ECORRUPT is not a wrong error code, it doesn't match other instances of hitting a corrupt block during write. During writes, if blocks are detected as corrupt their data is evicted and moved to a new clean block. This means that at the end of a disk's lifetime, exhaustion errors will be reported as ENOSPC when littlefs can't find any new block to store the data. This has the benefit of matching behaviour when a new file is written and no more blocks can be found, due to either a small disk or corrupted blocks on disk. To littlefs it's like the disk shrinks in size over time.
