You can try the following solution:

.list-group-horizontal .list-group-item {
  display: inline-block; 
}
.list-group-horizontal .list-group-item:focus {
  background-color: #41AADA !important; 
  color:#fff;
  display: inline-block;
}
.list-group-horizontal .list-group-item {
  margin-bottom: 0;
  margin-left:-4px;
  margin-right: 0;
}
.list-group-horizontal .list-group-item:first-child {
  border-top-right-radius:0;
  border-bottom-left-radius:4px;  
}
.list-group-horizontal .list-group-item:last-child {
  border-top-right-radius:4px;
  border-bottom-left-radius:0;   
}
.form-check label {
  padding:.75rem 1.25rem;
  margin-bottom:0;
}
.form-check label input[type="checkbox"] {
  opacity:0;
}
