That byte is created by OpenVPN in src/openvpn/ssl.c on line 1469: uint8_t header = ks->key_id | (opcode << P_OPCODE_SHIFT); On the page https://openvpn.net/community-resources/openvpn-protocol/ they explain that this is the packet opcode/key_id (8 bits) which consists of: packet message type, a P_* constant (high 5 bits) and: key_id (low 3 bits) Since this is the initial packet, the key_id is zero.
