As I said, it's ok to install 2-3 more tools that need to run along with lnd. Not more than that. Tools like lndg, thunderhub, RTL are obviously hugely convenient tools, but that also means that you expand your attack surface. Security comes at a cost of convenience and it's up to you to decide the trade-offs and accept lower convenience for higher security and evaluate for yourself if the loss in convenience is worth the gain (how much ever it maybe) in security.
