For better readability and maintainability, it's a good practice to define the set of excluded headers separately. Using a set is also more idiomatic and typically more performant for membership testing than a tuple.

Suggested change
headers = {
k: v
for k, v in backend_response.headers.items()
if k.lower() not in ("content-encoding", "transfer-encoding", "connection")
if k.lower()
not in (
"content-length",
"content-encoding",
"transfer-encoding",
"connection",
)
}
excluded_headers = {
"content-length",
"content-encoding",
"transfer-encoding",
"connection",
}
headers = {
k: v
for k, v in backend_response.headers.items()
if k.lower() not in excluded_headers
}


headers["X-Request-Id"] = request_id
