Can I search for sound labels such as Laughter, Music or Applause in subtitles?

Yes. Filmot indexes descriptive caption labels using placeholders such as #Laughter#, #Music# and #Applause#. Search them like ordinary terms, alone or combined with other words. For example, "#FUCK# #Laughter#"~10 finds censored positions near laughter.

Sound labels depend on the subtitle language, and YouTube's wording can change over time. Italian tracks may use #Risate#, #Musica# and #Applauso#. The censored-word placeholder #FUCK# is the exception: Filmot uses the same marker in every language.
