Yes, this is correct

Yes, this is correct too.

In both cases, the bitfield is preceded by the mention "little-endian" :
- " Block_Header uses 3 bytes, written using little-endian convention. It contains 3 fields "
- Literals_Section_Header: "It's a byte-aligned variable-size bitfield, ranging from 1 to 5 bytes, using little-endian convention."
"Little-endian" was presumed a "good enough" indication that the first byte is the lowest one.
After that, the "lowest bit" becomes the least significant bit of the first byte.
Nevertheless, if this is deemed not clear enough,
some additional statement could be added to make the specification more explicit.

Summary: This review primarily focused on the differences, which seem
appropriate, from the RFC.
Major issues: N/A
Minor issues: N/A
Nits/editorial comments:
I presume that bits within a byte are still interpreted in the normal
fashions since we do not work in terms of the serialization of bits on a
wire, and in fact different wires may do it differently. This does leave
the question of how bit fields are interpreted when they describe bits
within a byte. Thus, I assume that the "last block" flag is the least
significant bit of the first byte of the block header? And
Literals_Block_Type is the least significant two bits of the first byte of
the Literals_Section_Header? (I presume that the use of little-endian
encoding is due to existing practice, and therefore presume it is what this
needs to describe.) Should this be stated more explicitly?
