Yes, because you can always draw out what you are trying to say or you can use sign language unless of course you and the other person don't know sign language or if you consider that a language as well because it does have that in the name.
Answer:
It depends on who you are saying it to:
I love you - "ich liebe dich" this phrase is strictly used for your partner or spouse. This phrase is only suitable to be said to a person you are very close with and indicates a great deal of trust and familiarity.
I like you lots - "Ich hab’ dich lieb” (more common than “Ich habe dich lieb”) is probably your best choice. If you are looking for a more innocent way of expressing your like for someone, or if you’re talking to a very close friend or a parent.
